Question

How can we find electrical resistance????

Answer 1

V=I-R and the power of law equation P = I*V

Answer 2

☆☆ AS-SALAMU-ALYKUM ☆☆

DEFINITION :-
▪▪▪▪▪▪▪▪▪▪

RESISTANCE IS THE OPPOSITION OFFERED BY A SUBSTANCE TO THE FLOW OF CURRENT

FORMULA :-
▪▪▪▪▪▪▪▪▪

IT IS GIVEN BY A FORMULA
▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪

R=RHO ×L÷A

'RHO' IS RESISTIVITY

'L' IS LENGTH OF WIRE

'A' IS CROSS SECTION AREA OF WIRE


WE CAN USE THIS FORMULA TO FIND RESISTANCE

FACTORS AFFECTING RESISTANCE ARE :-
▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪


■ LENGTH OF WIRE

■ CROSS SECTION AREA OF WIRE

■ TEMPERATURE
