The resistance of a 24 W, 12 V filament lamp depends on the current flowing through the lamp. For currents up to 0.8 A, the resistance has a constant value of 2.5 Ω.

Calculate the potential difference across the lamp when a current of 0.8 A flows through the lamp.

Answer:

V=IR

V=0.8×2.5

V=2V

where V=potential difference

I=Current

R=Resistance
