Answer 2

Answer :

• a) Ohm

$\leadsto$ Ohm is the SI unit of electrical resistance.

Explanation :-

☯︎ Electrical resistance : Electrical resistance is a measure of the opposition to flow current in an electric circuit.

• Electrical resistance is symbolised by Ω (omega).
• SI unit of electrical resistance is ohm and $\bf 1 \ Ω \ = \ \dfrac {1 \ volt}{1 \ ampere}$
• There are some factors which affects the electrical resistance like : Length, thickness and temperature of the material.
• Resistance converts electrical energy into the thermal energy.
