Explain capacitor and rehostat???
Answers
Answer:
capacitor - A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance
rehostat - Rheostat is a variable resistor, which is used to control the flow of electric current by manually increasing or decreasing the resistance
Explanation:
rheostat
The electric current flowing through an electrical circuit is determined by two factors: the amount of voltage applied and the total resistance of the electrical circuit. If we reduce the circuit resistance, the flow of electric current through the circuit will be increased. On the other hand, if we increase the circuit resistance, the flow of electric current through the circuit will be decreased.
By placing the rheostat in the electrical circuit, we can control (increase or decrease) the flow of electric current in the circuit. Rheostat reduces the electric current flow to certain level. However, it does not completely blocks the electric current flow. To completely block the electric current flow, we need infinite resistance. Practically it is not possible to completely block the electric current.
A capacitor is a device that stores electrical energy in an electric field. It is a passiveThe effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensator.This name and its cognates are still widely used in many languages, but rarely in English, one notable exception being condenser microphones, also called capacitor microphones. electronic component with two terminals.
