A student uses a voltmeter.

(a)

State the quantity measured with a voltmeter.

______

(b)

Fig. 1.1 shows an analogue voltmeter.

Fig. 1.1

State the reading on the voltmeter.

reading = ______

(c)

A school has both digital and analogue voltmeters.
Suggest one advantage of using a digital voltmeter rather than an analogue voltmeter.

______

(d)

The student is asked to connect three $2.0\text{ V}$ cells in series with a resistor R of resistance $100\ \Omega$ . The student sets up the circuit as shown in Fig. 1.2.

Fig. 1.2

(i)

State the reading on the voltmeter when it is connected across

(1)

AD,

reading = ______

(2)

AB,

reading = ______

(3)

DC.

reading = ______

(ii)

R is replaced by a resistor of resistance $1000\ \Omega$ . There is no change in the reading on the voltmeter across DC. Explain this.
