Question

1- State Ohm's law 2- Draw a schematic diagram of circuit for verifying Ohm's law 3 List the factors on which the resistance of a conductor depends​

Answer 1

Explanation:

ANSWER

Ohm's law states that Current through a conductor is directly proportional to voltage difference across it.

IαV

⇒V = I R

where V is the voltage, I is the current and R is the resistance.

The circuit diagram to verify ohm's law is drawn below. Voltmeter across a resistor is connected in parallel. Ammeter to measure current in the circuit is attached in series. A variable resistor is connected. Changing the resistance would alter potential drop across the resistor which would affect the amount of current. From the reading we find that I and V vary linearly.
