PARAMETERS OF AN ELECTRICAL CIRCUIT

VOLTAGE

Voltage is the difference in charge between two points.

CURRENT

Current is the rate at which charge is flowing.RESISTANCE

Resistance is a material’s tendency to resist the flow of

charge.tut Term 4

RESISTORS

They resist flow of electric current.

Resistance measured by ohms law : R=V/I

Where, R-Resistance V-Voltage I-Current
