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 resi
stance 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.
1 answer:
Answer:
V=IR
V=0.8×2.5
V=2V
where V=potential difference
I=Current
R=Resistance
