[06.3] Students found this question difficult with very few scoring marks because of incorrect assumptions about how potential difference, current and resistance are affected by series and parallel circuits. Marking point 2 was dependent on marking point 1 so that students who stated that the current was increased without a valid reason would not score. The third mark was demanding in requiring an understanding of how P = IV related to the circuit being considered. Just over 80% of the students scored no marks.

[09.1] Many of the students did not convert the 70 cm into metres and some students converted the energy unnecessarily. Not converting the height stopped marking point 1 from scoring and converting the energy unnecessarily stopped 1 marking point from being scored too. Some students, despite setting out their calculations correctly, did not use brackets around the denominator and arrived at an answer of 0.0245 or 2.45. Nearly 80 % of the students scored full marks on this question.

Similarly, ‘not enough to give you a shock’ and ‘not enough to electrocute you’ were creditworthy for the second mark.

Most students thought that the student believed that power and p.d. were directly proportional but had done the calculation incorrectly, so the power should be 2.0 W not 4.0 W. Statements like ‘if power was proportional to p.d. then the power should be 2 W not 4 W’ were commonly seen and scored zero.

Question 07.1 discriminated well between students and there were multiple ways of arriving at the answer, using a selection of electricity equations. To score 2 marks in 07.2 students needed to select 3 sets of values to show that the constant was the same and very few students managed to do this. Many students simply stated that as one quantity increased, the other quantity decreased, revealing that they did not understand the term inversely proportional.

Question 10 was poorly answered across the question. Few students were able to explain the benefit of transmitting electricity at a high potential difference in 10.1. Many students stated, incorrectly, that static electricity was responsible for the danger involved in flying a kite near power cables. Question 10.3 was poorly answered and many students chose to continue the existing graph line, rather than draw their own. Very few students appreciated in 10.4 that the wires would behave as if they are in parallel, despite the question stating this.

[04.4] Only 5% of students scored 3 marks on this challenging question. Very few realised that the important factor was the change in resistance with temperature in the region of temperatures corresponding to the sea temperature values. The majority of students chose thermistor A ‘because it has the lowest resistance’. 18% of students scored 1 mark and 73% of students scored no marks.

Graphs compare UK coal- and gas-fired generation, mean sea-surface temperature from 1988–2016, and resistance-temperature curves for thermistors A–D. Sea-temperature samples (year, °C) are approximately (1988,16.45), (1990,16.40), (1991,16.51), (1993,16.38), (1996,16.49), (1997,16.45), (1998,16.67), (1999,16.45), (2001,16.60), (2004,16.66), (2008,16.58), (2010,16.72), (2011,16.62), (2014,16.72), (2016,16.95), joined by the official smooth irregular line. Approximate thermistor anchors (temperature °C, resistance kΩ) are: A (−75,10), (−50,5), (−25,1), (0,0); B (−50,>50), (−25,20), (0,8), (25,3), (50,1); C (−10,50), (0,35), (25,15), (50,7), (75,3), (100,1); D (50,50), (75,22), (100,12), (125,7), (150,4), (175,2), (200,1). Each is a smooth decreasing curve.

[08.4] This explanation was not well known, only 11% of students scored 2 marks, while 26% of students scored 1 mark. The most common answer was that ‘the resistance is shared’. Another common answer was to use the equation for resistors in parallel as an explanation. Of those students who had the correct idea, most gained a mark for stating that there would be multiple paths for the current to take, but very few were able to progress to the idea that the total current in the circuit would be greater.

[09.1] 53% of students scored 5 marks on this multi-step calculation. Lower-scoring students didn’t score marks for stating and trying to use incorrect physics equations or rearranging correct equations incorrectly. The main reasons for not scoring full marks included: knowing one form of an equation correctly, but re-arranging it incorrectly, eg stating P = I V then re- arranging it to I = V/P, mixing up two half-known equations eg P = I2 V, not realising that the 5 marks for this question warranted more than using one basic equation, eg stating R = V/I and substituting the given value of power for I.

A fault in a 230 V household lighting switch gives a mild electric shock. Mean power transfer to the person is 5.75 W. Maximum let-go current (mA) against frequency (Hz) is a smooth U-shaped curve through approximately (5,12.5), (10,12), (20,10.5), (30,9.5), (40,9.0), (50,8.8), (60,9.2), (70,10.0), (80,11.2), (90,13.2), (100,15.7). UK mains is 50 Hz.

[07.2] Approximately 83% of students answered this question correctly. Students should refer to the Physics specification for the accepted symbols for circuit components. Textbooks and revision guides do not necessarily use the specification symbols. The circles in the component symbol scored a mark even if shown as blobs rather than circles.

A circuit has a battery and ammeter feeding two parallel lamp branches. Candidate switch positions J and L are on opposite sides of one lamp branch, K is on the other lamp branch, and M is on the common supply return. Two further circuits use identical components: Circuit X has two lamps in parallel; Circuit Y has two lamps in series.

A student investigates a filament lamp. Figure 6 is a smooth resistance-current curve passing approximately through (0.30 A,7.0 Ω), (0.40 A,7.4 Ω), (0.50 A,8.4 Ω), (0.60 A,9.8 Ω), (0.70 A,12.0 Ω), (0.74 A,13.5 Ω). Figure 7 shows Graph A as a symmetric curved I–V line whose gradient decreases away from the origin; Graph B as a straight line through the origin; Graph C with almost zero reverse current and a steep forward-current rise after a threshold.

A 12 V circuit has an ammeter, a resistor R and a 45 Ω resistor in series. A 60 Ω resistor is also in series while switch S is open; closing S short-circuits the 60 Ω resistor. With S open, the ammeter reads 0.10 A.

An electrician replaces an old electric shower. The UK live wire is at 230 V and the electrician is at 0 V. A graph relates recommended maximum power input to wire cross-sectional area; near 13.8 kW the curve passes through about (9.0 mm<sup>2</sup>, 13.2 kW) and (10.0 mm<sup>2</sup>, 14.0 kW). The new shower has power 13.8 kW. In 300 s, 18 000 C flows through it.
