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=(V)/(R)`

So:

`I=(30.0V)/(10.0\Omega)\Rightarrow I=3A`

So, the current is 3 Amps.
