In the given circuit, what is the current (in A) through the battery?

A 5V battery is connected to two 20 Omega resistors which are joined together in series. (a) Draw a circuit diagram to represent this. Add an arrow to indicate the direction of conventional current flow in the circuit. (b) What is the effective resistance of two resistors? (c) Calculate the current that flows from the battery. (d) What is the p.d. across each resistor?

What is the total current supplied by the battery to the circuit shown ?

The potential difference across the terminals of a battery is 8.4 V when there is a current of 1.50 A in the battery from the negative to the positive terminal. When the current is 3.50 Air , the reverse direction, the potential difference becomes 9.4 V . (a) What is the internal resistance of the battery? (b) What is the emf of the battery?
