Question
The voltage across the ends of a resistor is wtVv sin0= . The r.m.s.value of this voltage is :
Solution
The root mean square (rms) value of a sinusoidal wave is given by the peak value divided by the square root of 2.
Given the peak voltage V = wtVv, the rms voltage (Vrms) can be calculated as follows:
Step 1: Identify the peak voltage (V). In this case, V = wtVv.
Step 2: Apply the formula for rms voltage, which is Vrms = V/√2.
Step 3: Substitute the given peak voltage into the formula. So, Vrms = wtVv/√2.
So, the rms value of the given voltage is wtVv/√2.
