Q. A Single Phase Neutral (SPN) electrical circuit has a power consumption of 330W. Considering a voltage of 110V and power factor of 0.8, the electrical current drawn is
Ans: 3.7 to 3.8
Sol:
3.7 to 3.8
Power (Watts) = Voltage (Volt) × Current (Ampere)
(P = V × I × power factor)
Here, 330 W = 110 V × Current (Ampere) × 0.8 (Power Factor)
Thus, Current [I] = 3.75 Ampere
