three wires of resistances 20, 24, and 30 ohm are arranged in
1)series
2)parallel arrangements. Find the equivalent resistance of the circuit in each situation
Answers
1. Resistance ( in series),
R = R1 +R2+R3
=> 20+24+30
=> 64 ohm

➛Resistance is always maximum in series whereas lowest in parallel connection.
➛Ammeter is a device used to measure current in a circuit.
➛Ammeter is always connected in series connection in circuit.
➛Voltmeter is a device used to measure potential difference (or voltage) in a circuit.
➛Voltmeter is always connected in parallel connection with circuit.
