Q3. What is ragistance
Ans. 
Resistance is the opposition to the flow of electric current in a circuit.
• Resistance is measured in ohms (Ω).

• It is caused by factors such as the material of the conductor, its length, and its cross-sectional area.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• Higher resistance leads to lower current flow.

• Examples of resistance include the filament in a light
