A potentiometer circuit consists of a battery of emf 5V and internal resistance 1ohm connected in series with a 3ohms resistor and a potentiometer wire AB of 1.0m length.
1. Calculate the total resistance of the circuit.
2. The current flowing in the circuit
3. The lost voltage from the internal resistance of the battery terminals
4. The pd across wire AB
5. The emf of a dry cell which can be balanced across 60 cm of the wire AB
