Question

what do you understand by a) voltage b) electric current ?​

Answer 1

Answer:

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing.

Electric Current: The flow of electric charge is known as electric current. Electric current is carried by moving electrons through a conductor. ... Electric current is expressed by the rate of flow of electric charges. Rate of flow means the amount of charge flowing through a particular area in unit time.

Answer 2

(A)Voltage : Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).

(B) Electric current : An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.
