Resistance Conductance & Ohm's Law

RESISTANCE

The opposition to the flow of electron is called resistance.

OR

Resistance is the property of a material due to which it opposes the flow of electric current. "R" represents it. It, s unit is called ohm. Ohm is represented by omega (Ω)

Mille Ω = 10-3Ω

Micro Ω = 10-6Ω

Nino Ω = 10-9Ω

Pico Ω = 10-12Ω

133Ω = 1 kilo Ω

106Ω = 1 mega Ω

OHM

When one volt is given to a circuit due to which one-ampere current flows then the curcuit resistance will be 1Ω.

OR

The resistance will be one ohm when ampere current flows in a circuit in one second and one-joule energy produce.

Conductance

Conductance is the propertey of material due to which it allows the flow of electric current. "G" represects it. It unit is called Simon.
