Question

In a circuit with one 12.0 resistor, a current of 0.500 A is flowing. This circuit is powered by a single

battery. What is the voltage of the battery?​

Answer 1

6 V

Step-by-step explanation:

In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:

`V=RI`

where

V is the voltage

R is the resistance

I is the current

In this circuit, we have

`R=12.0\Omega` is the resistance

I = 0.500 A

so we can find the voltage of the battery by using Ohm's law:

`V=(12.0 \Omega)(0.500 A)=6 V`
