(b) If the combination is connected to a battery of emf 6V and internal resistance 0.5Omega , find the current drawn from the battery and terminal potential difference across the battery.

A 4 V battery of internal resistance 1 Omega sends a current through a 3 Omega resistor. The terminal p.d. is

A potentiometer wire has a resistance of 20 Omega and length 10 m. It is connected in series with a battery of emf 2.5 V and negligible internal resistance, and an external resistance of 5 Omega . Fall of potential in mV per metre is

The storage battery of a car has an emf of 12 V. If the internal resistance of the battery is 0.4 Omega what is the maximum current that can be drawn from the battery ?

Two resistors are connected in series with 5V battery of negligible internal resistance. A current of 2 A flows through each resistor. If they are connected in parallel with the same battery a current of (25)/(3)A flows through combination. Calculate the value of each resistance.
