State Ohm's Law. Draw a circuit diagram...

State Ohm's Law. Draw a circuit diagram to verify this law indicating the positive and negative terminals of the battery and the meters. Also show the direction of current in the circuit .

Text Solution

Verified by Experts

Ohm.s Law : It states that "Physical conditions remaining same, the current flowing through a conductor is directly proportional to the potential difference across its two ends".
i.e., `V alpha I`
`V = IR `
where the constant of proportionality R is called the electrical resistance or resistance of the conductor. Diagram to Verify Ohm .s Law :
