Why is a transformer rated in KVA?

All electrical devices are rated based on the maximum power it can consume or generate or transfer. When few of them are rated in KW (kilowatts) or watts, few others…

What is meant by stalling of motor?

Stalling is a condition at which a motor stops rotating even when there is sufficient voltage at it’s terminals. This condition occurs when the torque required by the load is more than the maximum torque (Breakdown torque) that can be generated by the motor. At this condition, the motor drains the maximum current and the speed comes zero.
