1. State Kirchhoff's laws and apply them to the solution of the following problem. Two batteries, A and B, are connected in parallel, and an 80 Q resistor is connected across the battery terminals. The e.m.f. and the internal resistance of battery A are 100 V and 5 2 respectively, and the corresponding values for battery B are 95 V and 3 2 respectively. Find (a) the value and direction of the current in each battery and (b) the terminal voltage.

Exercises 4 1. State Kirchhoff's laws and apply them to the solution of the following problem. Two batteries, A and B, are connected in parallel, and an 80 resistor is connected across the battery terminals. The e.m.f. and the internal resistance of battery A are 100 V and 5 2 respectively, and the corresponding values for battery B are 95 V and 3 Q respectively. Find (a) the value and direction of the current in each battery and (b) the terminal voltage. 2. State Kirchhoff's laws for an electric circuit, giving an algebraic expression for each law. A network of resistors has a pair of input terminals AB connected to a d.c. supply and a pair of output terminals CD connected to a load resistor of 120 Q. The resistances of the network are AC= BD = 180 Q, %3D and AD = BC = 80 Q. Find the ratio of the current in the load resistor to that taken from the supply.
