Context for question 3

A student investigates circuits containing different combinations of resistors.

3(a)(i)Easy1 mark

Figure 3.1 shows circuit 1.

Figure 3.1, circuit 1 with a cell and switch in series with an ammeter, and a voltmeter connected across a single resistor

Circuit 1 contains one resistor of resistance

X Ω

. The student closes the switch and measures the potential difference (p.d.) and current. Record, in Table 3.1, the voltmeter and ammeter readings shown in Figure 3.2 for circuit 1.

3(a)(ii)Easy1 mark

Figure 3.3 shows circuit 2.

Figure 3.3, circuit 2 with a cell and switch in series with an ammeter, and a voltmeter connected across two parallel branches, each branch made of two identical resistors in series

Circuit 2 contains four identical resistors each of resistance

X Ω

. The student closes the switch and measures the potential difference (p.d.) and current. Record, in Table 3.1, the voltmeter and ammeter readings shown in Figure 3.4 for circuit 2.

Voltmeter and ammeter readings

3(a)(iii)Medium3 marks

Calculate, and record in Table 3.1, the resistance of each circuit. Give your answers to 2 significant figures. Use your readings from Table 3.1 and the equation shown.

R = \frac{V}{I}

Answer (resistance of circuit 1 and circuit 2)

3(a)(iv)Medium2 marks

Theory suggests that the resistance of circuit 1 and circuit 2 are the same. State whether the results support this suggestion. Justify your statement by reference to values from your results.

Your answer

3(a)(v)Easy1 mark

Figure 3.5 shows circuit 3.

Figure 3.5, circuit 3 with a cell and switch in series with an ammeter, and a voltmeter connected across three parallel branches, each branch made of three identical resistors in series

Circuit 3 contains nine identical resistors each of resistance

X Ω

. Predict the resistance of this combination of resistors.

Your answer

Context for 3(b)

Another student performs the same experiment but uses a digital ammeter.

3(b)(i)Easy1 mark

State one advantage of using a digital meter.

3(b)(ii)Easy1 mark

Figure 3.6 shows a digital ammeter display when it is connected in a circuit. Record the value for the current shown in amperes.

Answer

3(c)Medium2 marks

Suggest two reasons why the switch is opened after readings are taken.

Reason 1

Reason 2
