What is a FET transistor?
FET is based on the concept that charging on a nearby object can attract charges within a semiconductor channel. FET is made up of a semiconductor channel with electrodes at…
What is the basic function of a transistor?
One of the most common uses for transistors in an electronic circuit is simple switches. In short, a transistor drives the current across the collector-emitter trajectory only when a voltage…
What is a transistor and how are they used?
A transistor is a semiconductor device used to amplify or switch electronic signals and electricity. It is made of semiconductor material, usually with at least three terminals for connection to…
What is a capacitor used for in an electric motor?
An engine capacitor such as a starter capacitor or a driving capacitor (including a dual-stroke condenser) is an electric capacitor that alters the current to one or more windings of…
What is the purpose of a capacitor in an AC circuit?
During this charging process, a charging current (i) will flow to the capacitor opposite any voltage change at a rate equal to the charge rate of the electrical charge on…
How do you jump start a positive ground vehicle?
A jump start, also known as boost, is a method to start a vehicle with a booted discharge battery. A temporary connection to the battery of another vehicle or to…
Can current be negative?
Can current be negative? As from question you thought that its wrong, but no friend question is right but current is never negative but its calculation at end its as…
How is a capacitor different from a battery?
Batteries and condensers seem similar because they store and release electricity. However, there are key differences between them that affect their potential applications due to how they work differently. A…
Can there be a potential difference without current?
The electric potential is the potential electric power per unit charge, measured in joules per coulomb (volts). The “electric potential” must be distinguished from the “electric potential” by noting that…
What would happen to the voltage if you increase the resistance or what is varistor?
A varistor is an electronics component with an electrical resistance that varies with applied voltage. Also known as a voltage-dependent resistor (VDR), it has a non-linear, non-ohmic current characteristic that…
