WebFeb 11, 2024 · their work clearly showed how the resistance of the resistor approximated to 400Ω. Weaker students knew to use Ohm’s Law and often rearranged this correctly with a valid data substitution to gain 2 marks, but struggled to make further progress due to not converting milliamps to amps. Q6(b) was poorly answered by all but the most able students. Web3 A student investigates resistance. Fig. 3.1 shows the circuit used. power supply A V resistance wire sliding contact S B C D l R Fig. 3.1 (a) The student measures the current I in the circuit. He places the sliding contact S at C and measures the potential difference (p.d.) V 1 across the resistor R. The voltmeter and ammeter are shown in Fig ...
