Step 1

1 of 2In this problem we have to calculate the current through a resistor $R=47\,\mathrm{\Omega}$ if a voltage difference across it is $\Delta V=8\,\mathrm{V}$.

To calculate the current through this resistor, we will use the Ohm's law:

$\begin{aligned} &I=\frac{\Delta V}{R} \\ &I=\frac{8}{47} \\ &\boxed{I=0.17\,\mathrm{A}} \end{aligned}$
