The direction of the current flowing through it must be changed after every half rotation. Otherwise, when the north pole of the coil comes near the south pole of the magnet, there will be attraction between them and the coil will stop rotating.
The electric force that makes current flow in a circuit is related to the resistance.
A PN diode is a semiconductor device that allows current to flow primarily in one direction. It consists of a p-type region (with positive charge carriers, or holes) and an n-type region (with negative charge carriers, or electrons). When forward-biased, the diode conducts current, while in reverse bias, it blocks current flow. This property makes PN diodes essential for rectification, signal modulation, and various electronic applications.
Voltage commutation: This is possible in ac circuits...The thyristor gets turned off by reverse bias (negative half cycle) voltage applied across it. This is also called line commutation. Current Commutation: This is possible in dc circuits ...This type of commutation makes use of auxiliary circuit which contains inductor,capacitor,diode and even a thyristor(auxiliary). This is called Forced commutation.
IF there is a Resistor
Rephrase your question so that it makes sense.
Of course. If you take the batteries out of a flashlight and put them back in pointingthe other way, the current goes through the bulb in the opposite direction.It's so easy to reverse the flow of electric current that . . .-- the current coming out of a household electric socket reverses 120 times every second,-- the current in the antenna of your FM radio reverses roughly 200 million times every second-- the current in the antenna of your cellphone reverses almost 2 billion times every second,-- the current in the magnetron that makes the microwaves that heat your leftover meat loafreverses 4.9 billion times every second.
The structure of the heart is what makes it an efficient pump. It works continuously without tiring, and it receives electric signals every second and pumps blood nonstop.
due to commutation the current in the coil reverses
A man continuously makes sperm for all of his life.
Schottky diodes are used in reverse bias applications primarily because of their low forward voltage drop and fast switching capabilities. In reverse bias, they can effectively block reverse current due to their unique metal-semiconductor junction, which allows for minimal leakage current compared to conventional diodes. This makes them ideal for high-frequency and low-voltage applications, such as in power supplies and RF circuits, where efficiency and speed are crucial.

The business of a business is ECONOMICS itself. What makes ECONOMY continuously flow is business. What makes countries innovate is business. What generate jobs is business. What creates improvement projects are business. Almost every aspect of business is primarily targeted in terms of ECONOMIC flow.
For the working of TTL nand with totempole When both inputs are LOW The emitter base junctions at A and B gets forward biased, base -collector junction gets reverse biased for Q1.So maximum current flows through forward biased junction. As base -collector junction of Q1 gets reverse-biased, base current through the Q2 is ZERO, which makes Q2 OFF. As Q2 is in OFF state, base current through Q4 is ZERO, which makes Q4 OFF.As Q2 is in OFF state the current through R2 flows through base of Q3 which makes Q3 and diode D to ON.As Q4 is in OFF state the current flows through the load, which make output to go HIGH state
sense question Your makes no.

The fractional change due to intensity on minority charge carriers is more than on majority charge carriers. When light is directly polarized it acts like a normal diode but when reverse polarized its current depends on the brightness (intensity of incident light).
Resistance in the circuit makes it difficult for current to pass through.
