Step 1
1 of 3Given:

A DC circuit with the following specifications:
 It has a battery of voltage $V=12\text{ V}$.
 It has a resistor of electric resistance $R=5\,\Omega$
Required:
 To determine the electric current $I_r$ flowing through the resistor.
Context:

Since there are no specifications, we will assume that the battery and the resistor are connected in series.

This problem can be solved using Ohm's law, which adapted to this case, would be given by:
$V=I_r\cdot R\tag 1$
