- Homework Statement
- Calculate EMF of E1

- Relevant Equations
- V=IR

E=IR1+IR2

I=I1+I2

My initial solving method was taking 1.75A and adding the resistors at the 1st loop(4 and 8 ohms) to get the answer

V=IR

V=1.75(4+8)

V=21V

But the answer sheet uses 0.75A instead of 1.75A to find EMF of E1.

So according to the answer sheet its

V=0.75(4+8)

V=9V

0.75A is the answer for the i) question. And I am confused as to why use 0.75 instead of 1.75. Isn't 1.75A the current transferred by the E1 battery since its even coming from the direction of E1?
