AC Applied to a Resistor

A resistance ...

Question

A resistance of $20 Ω$ is connected to a source of alternating current rated $110 V, 50 H z$ Find the $r m s$ current.

Open in App

Solution

The root mean square value of the current is given as,

$I_{r m s} = \frac{V_{r m s}}{R}$

$= \frac{110}{20}$

$= 5.5 A$

Thus, the rms value of the current is $5.5 A$ .
