Part a what must the emf in the figure be in order for the, Ask an Expert

Academics

Part A) What must the emf in the figure be in order for the current through 7.00-OHM resistor to be 1.76 A? Each emf source has negligible internal resistance.

Part B) What is the amount of current through the 24.0-V battery?

Part C) What is the amount of current through the 2.0-OHM resistor?

For part A, The answer is 8.05V. I know what the set up looks like, The set up looks like 0 = 24V-((1.76A*7OHM)) - I(3OHM).. but can you please show how to set that up?

I also would like step-by-step instructions on how to set up and solve B and C.
