An alternating voltage given by `V=70 sin 100 pi t` is connected across a pure resistor of `25 Omega.` Find
(i) the frequency of the source.
(ii) the rms current through the resistor.

Explanation

To solve the problem step by step, we will break it down into two parts as required: finding the frequency of the source and calculating the RMS current through the resistor.

### Step 1: Find the frequency of the source

1. The given voltage equation is:
\[ V = 70 \sin(100 \pi t) \]
