Question

The current in the circuit shown is 5.0 A, and the resistor is 2.0 2 What is the potential across the battery?A. 10 VB. 3.0 VO C. 8.0 VOD. 2.5 V

Answer 1

Given that the current is I = 5 A

The resistance in the circuit is

$R=\text{ 2 }\Omega$

We have to find the potential across the battery, V.

According to Ohm's law, the potential across the battery will be

$V=IR$

Substituting the values, the potential will be

$\begin{gathered} V=5A\times2\Omega \\ =10\text{ V} \end{gathered}$

Thus, option A is correct.
