Question

Given a circuit with a DC battery of voltage 30.0 volts connected to a single resistor of resistance 10.0 ohms. Which of these is the current through the resistor in SI units?A)12B)18C)3D)0.333E)15

Answer 1

We will determine the current as follows:

First, we remember that:

$I=\frac{V}{R}$

So:

$I=\frac{30.0V}{10.0\Omega}\Rightarrow I=3A$

So, the current is 3 Amps.
