What is Reverse Saturation Current of a diode?
When a diode is operated as reverse bias the current flow is almost completely blocked. A small amount of current is still able to travel in reverse through the diode and this is referred to as the reverse current saturation.
When is the collector current maximum?
The maximum collector current is normally rated to be the current at which the DC current gain (hFE) falls to 50% of its maximum value. The maximum peak current is Page 2 Operation notes Transistors Rev.A 2/7 rated at a value which ensures reliability within the maximum allowed junction temperature.
Why the armature rheostat of dc is motor kept at maximum resistance position?
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
Why use maximum resistance for starting dc shunt motor?
because there is ahigh current flowing through it at the start...
What is the difference between 1n4004 diode and 1n4007 diode?
The main difference between a 1n4004 and a 1n4007 are in the maximum RMS voltage, the maximum DC blocking voltage and the maximum repetitive peak reverse voltage. These are 280 and 700, 400 and 1000, and 400 and 1000 volts respectively.
What is maximum reverse current?
this is the best current.

What is strong the DC or the ac?
DC, or direct current, is stronger than AC, or alternating current. The reason for this is because DC current is smooth and unvariable as opposed to AC which varies from zero to whatever the maximum is, and then goes back to zero once again.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
What does AC and DC stand for in electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.

What is ac current and DC current?
AC: Alternating CurrentThe current oscillates cyclically between a maximum and an minimum.DC: Direct CurrentThis is fixed. The current is always at a constant value.
Why the armature rheostat of dc is motor kept at maximum resistance position?
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
Current that reverses direction in the regular pattern is called?
This is known as a direct current or DC. The two major types of currents are AC (alternating current) and DC (direct current). In AC the charges move back and forth, but in DC the charges flow in JUST ONE DIRECTION. Due to this characteristic it will not reverse direction like AC can.
How does current flow in a nonreversing motor?
If you are talking polarity. DC motors automotive application run poss to neg. But any dc motor can reverse by changing polarity.
Why use maximum resistance for starting dc shunt motor?
because there is ahigh current flowing through it at the start...
