Question

using the symbols to write the equation/answers 

Current =I, Battery = E, Resistor = R, internal resistance = r, voltage= V

 

a) write down the relationship between the currents I1, I2 and I3. (example E1=I1R1)

b) write down the equation relating voltage for the upper loop

c) write down the equation relating the voltage for the lower loop

d) calculate the currents I1, I2 and I3 (example answer 0.00 unit)

The circuit in figure X below shows 5 resistors R1, R2, R3, R4 and R5 are connected to batteries E1, E2 and E3. Neglect the
internal resistance of the batteries.
R3= 10
E, = 9 V
Rg= 22
R2 = 30
Ez= 3 V
R= 20
R= 10
E, = 10 V
