Asked by Usoro

A battery of emf 12v nd internal resistance (r) 1.5votls is connected to an external resistance (R) of 3ohms. (1.) Cal, the current flowing in the circuit. (2,) the p.d draw across the 3ohms resitor and the internal resirtance. (3) determine Voltage of the battery and comment of the result. (4) the reading of a volt metre connected across the batter therminal in the open circuit

The current is 2.67 amps
Potential drop across the 3 ohms is 8.01
Potential drop across internal resistance is 4.005
