Question 1
F

Figure shows two lamps, P and Q, connected in parallel with a cell. Three ammeters, A1, A2 and A3, are used to measure the currents in the circuit.

a.

A2 reads 0.30 A and A3 reads 0.45 A. Determine the reading on A1.

[1]
b.

The current in lamp Q is larger than the current in lamp P. Explain what this shows about the resistance of lamp Q.

[2]
c.

The filament in lamp P breaks. Explain the effect on the reading on A3.

[2]
d.

Give one advantage of connecting the two lamps in parallel rather than in series.
