a) The peak voltage of an ac supply is 300 V. What is the rms voltage? (b) The rms value of current in an ac circuit is 10 A. What is the peak current?
a)
Given: The peak voltage of supply is 100 V .
The rms voltage is give as,
v m = 2 × V
Where, the peak value of supply voltage is v m and its rms value is V .
By substituting the given values in the above equation, we get
300 = 2 × V V = 300 2 = 212.1 V
Thus, the value of rms voltage is 212.1V.
b)
Given: The rms current in an ac circuit is 10 A .
The peak current in the circuit is given as,
i m = 2 × I

By substituting the given values in the above equation, we get
i m = 2 × 10 = 14.1 A
Thus, the value of peak current in the given ac circuit is 14.1 A .
