A $47\Omega$ resistor in a circuit has an $8\mathrm{~V}$ voltage difference across its leads. How much current flows through this resistor?

Quizlet Admin · Accepted Answer

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