Question 64
Easy

A student investigates how the total resistance of a circuit changes when lamps are added in parallel.

The student sets up a circuit containing a cell, an ammeter, and three identical lamps connected in parallel.

The circuit is shown in Figure 1.

Circuit diagram showing a cell connected in series with an ammeter. The circuit then splits into three parallel branches. Each of the three branches contains a single lamp. The branches recombine before returning to the cell.

On Figure 1, draw a voltmeter connected to measure the potential difference (voltage) across the parallel combination of lamps.
