Question

what do you mean by electric current and circuit​

Answer 1

Answer:

Rate of change of electric charge is called electric current

I=Q/T

SI unit is Ampere(A)

A circuit contains resistors,capacitors,connected by wires(conducting)

Answer 2

Electric Current:

The rate of flow of charge is termed as electric current. It is represented by "I".

Mathematically,

Electric current = $\sf{\dfrac{Charge}{Time}}$

$\implies$ I = $\sf{\dfrac{Q}{t}}$

Where, Q refers to charge, t refers to time and I refers to electric current.

S.I unit :

The S.I unit of electric current is Ampere.

1 Ampere :

" Electric current is said to be of one Ampere when a coulomb of charge flows in one second through any conductor. "

$\rule{200}2$

Electric circuit:

The closed path through which current flows is termed as electric circuit.

Some parts :

• Battery/cell
• key
• bulb
• resistance
• resistor
• voltmeter
• variable resistance
