Question 9

A student is building a portable camping lantern.

a.

The lantern requires a potential difference (p.d.) of 12.0 V12.0\text{ V}12.0 V. The electromotive force (e.m.f.) of each individual cell is 1.5 V1.5\text{ V}1.5 V.

State the number of cells that the lantern needs.

[1]
b.

Describe how these cells, the lamp, and a switch should be connected to form a functioning circuit.

[2]
c.

When the lantern is turned on, the potential difference across the lamp is 12.0 V12.0\text{ V}12.0 V and the current is 0.40 A0.40\text{ A}0.40 A.

Calculate the resistance of the lamp.

[2]
d.

Calculate the power of the lamp.
