A battery of `9 V` is connected in series with resistors of `0.2 Omega, 0.3 Omega, 0.4 Omega, 0.5 Omega and 12 Omega`. How much current would flow through the `12 Omega` resistor ?

Current flowing through 4 Omega resistor is :

Find the current through 12 Omega resistor in

Two cells E_(1) " and " E_(2) of emfs 4 V and 8 V having internal resistances 0.5 Omega " and " 1.0 Omega respectively are connected in opposition to each other. This combination is connected in series with resistances of 4.5 Omega " and " 3.0 Omega . Another resistance is connected in parallel across the 3 Omega resistor. (a) Draw the circuit diagram (b) Calculate the total current flowing through the circuit.

Three cells of emf 2.0 v, 1.8 V and 1.5 V are connected in series. Their internal resistances are 0.05 Omega, 0.7 Omega " and " 1 Omega respectively. If the battery is connected to an external resistor of 4 Omega via a very resistance ammeter, what would be the reading in the ammeter ?

A cell of emf 2V and internal resistance 4 Omega is connected across a parallel combination of two resistors of resistance 10 Omega and 20 Omega . Find the current through each resistor using Kirchhoff's laws.
