Q2. What is reagistance
Ans. 
Resistance is the opposition to the flow of electric current in a circuit.
• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a conductor.

• Higher resistance leads to lower current flow in a circuit.

• Examples of resistors include light bulbs, heating elements, and electronic components.

• Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.
