#### Solution Preview

This type of circuits can be solved using Kirchaff's laws.

The first law says that at any junction in the circuit the net current is zero or the total inward current is equal to the total out ward current and hence applying this law at the junction point B we have

I1 + I2 = I3 ---------- (1)

The second law says that the total drop in potential in a closed loop is equal to the total EMF in the circuit

Or

Where E is the EMF of a cell, I is the current and R is the ...

#### Solution Summary

The electrical circuit with number of resistances and batteries is given and the current in each resistor and the power drawn from the sources are calculated using Kirchoff's laws.
