Power consumed = Current x Voltage
= 2.2 x 200
= 484 watt.
The peak voltage of an ac supply is 300 V. What is the rms voltage?
Using the relation,
The rms value of current in an ac circuit is 10 A. What is the peak current?
Hence, using the formula,
which is the required value of peak current.
A 44 mH inductor is connected to 220 V, 50 Hz ac supply. Determine the rms value of the current in the circuit.
Inductance, L = 44 mH =
