Question

An electric device operates at $24V$and has a resistance of $8\Omega$. Calculate the current flowing through the device.

Answer 1

Step 1: Given data

Potential difference, $V_p=24V$

Resistance of the device, $R=8\Omega$

Current flowing through the device, $I=?$

Step 2: Formula used

$I=\frac{V_p}{R}$ …………………….(a)

Step 3: Calculation of the current flowing through the device

Substituting the given values in equation (a), we get

$$\begin{gathered} I=\frac{24V}{8\Omega } \\ I=3A \end{gathered}$$

Hence, the current flowing through the device is equal to $3A$.
