Question

An alternating Voltage is given by e=35sin314t is connected across a pure resistor of 50ohm . Then find 1) Frequency of source
2) rms of current through resistor ​

Answer 1

$\tt \epsilon = 35sin314t \\ \\ \tt Comparing\:this\:with \: \epsilon = {\epsilon}_{0}sin \omega t \\ \\ \tt \omega = 314 \\ \\ \tt 2\pi n = 314 \\ \\ \tt \boxed{\bold{\underline{\green{ n = 50 }}}} \\ \\ \tt {\epsilon}_{rms} = \frac{{\epsilon}_{0}}{\sqrt{2}} \\ \\ \tt {\epsilon}_{rms} = \frac{35}{\sqrt{2}} \\ \\ \tt \boxed{\bold{\underline{\green{\tt {\epsilon}_{rms} = 24.74 V }}}}$
