To determine the reactive power of the circuit, we need to first calculate the apparent power. The apparent power (S) is given by the formula:
S = V * I
Where V is the voltage and I is the current.
Given that the voltage (V) is 100V and the current (I) is 5A, we can substitute these values into the formula to calculate the apparent power:
S = 100V * 5A
S = 500 VA
The reactive power (Q) is then given by the formula:
Q = sqrt(S^2 - P^2)
Where P is the active power. Since the coil has only resistance, there is no reactive power. Therefore, the reactive power of the circuit is 0 VA.
A coil has resistance of 10 ohm and draws a current of 5A when connected across 100V, 50 Hz source Determine the reactive power of the circuit ?
