Question

Rory uses a battery to power a light bulb with a resistance of 10 Ω. If 0.15 A of current is flowing, what is the voltage of the battery?

Answer 1

Answer:

The voltage of the battery is 1.5 v

Explanation:

Given that, Rory uses a battery to power a light bulb with a resistance of 10 Ω. We have to find the voltage

For current, we can use the Ohm's law.

Mathematically, it can be written as:

V = IR

$V= 0.15 [A]* 10 [Ω]$

V = 1.5 Volts

So, the voltage of the battery is 1.5 v
