Answer to Question #117337 in Electric Circuits for a

Question

What is the voltage of a battery in a circuit if the total current is 2.5 Amps and the total resistance is 8 ohms?

Answer 1

The total current is $I=2.5 A$. The total resistance is $R=8\Omega$. Due to Ohm's law the voltage of a battery in a circuit should be $V=I\cdot R=2.5A\cdot 8 \Omega=20 V$.

Answer: the voltage of a battery is 20V
