as voltage on the gate increases it will reach a point where any further input will not effect further.

What is stall condition of motor?

Stoll condition of a motor or Stall torque is the torque which is produced by a device when the output rotational speed is zero. It may also mean the torque load that causes the output rotational speed of a device to become zero - i.e. to cause stalling.Stalling is a condition when the motor stops rotating.This condition occurs when the load torque is greater than the motor shaft torque i.e. break down condition.In this condition the motor draws maximum current but the motor does not rotate.The current is called as Stalling current.


What does it mean to source current?

the source current is the current that flows from the power source.


What mean by va in current transformer?

Its simply multiplication of voltage applied and current.


What precaution one must take while measuring AC on DMM?

1. Digital multimeters are very high impedance, they therefore draw very little current from the circuit under test. This makes them very sensitive to stray voltages. A voltage reading may not neccessarily mean that there is a useful voltage available on the circuit under test. Take readings other than expected, with a pinch of salt. Understand the circuit under test.2. A varying, or fluctuating voltage on the circuit under test, is not easy to see from digits. The numbers may just appear to change at random, whereas with an analogue meter, a pulse or variation will be easy to see from the needle movement.


Are resistor heating affected by line frequency?

No. The heating effect is the product of the square of the current and resistance, where the current is a root-mean-square value.A.C. current is always expressed as a root-mean-square (r.m.s.) value, which is equivalent to a d.c. current which produces exactly the same heating effect. Root-mean-square values are affected by the shape of a waveform, but not by its frequency.
