this is the best current.
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.
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.
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
because there is ahigh current flowing through it at the start...
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.
this is the best current.
direct current
Direct current (DC) does not reverse its direction of flow. This means that the flow of electrical charge in a DC circuit always moves in one direction, from the positive terminal to the negative terminal.
Direct current (DC) is the term used to refer to current that flows in one direction and does not reverse its direction. This is in contrast to alternating current (AC), which changes direction periodically.

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.
The maximum current capacity of a 9-volt DC battery will depend on the specific type and size of the battery. However, for a typical alkaline 9-volt battery, the maximum current output can range from around 500mA to 1000mA. It is important to check the specifications provided by the manufacturer for the exact current rating of the specific battery model.
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.
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.
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.
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
