Problem: (a) Find the emf ε1 in the circuit of the figure (Figure 1) .(b) Find the emf ε2 in the circuit of the figure.(c) Find the potential difference of point b relative to point a

FREE Expert Solution

We need three equations—Kirchhoff's loop rule:

V=0 around each loop

Kirchhoff's junction rule:

iin=iout at each junction

and Ohm's Law

V=iR

We don't know i3, but we know the other two currents, all the resistances, and one of three EMFs/voltages. Three unknowns: we need three equations.
