Problem

Above we have a simple circuit consisting of two batteries and for equivalent 1Ω resistors. The direction of all relevant currents have been defined as I1, I2, and I3.

Part A) Provide the loop equation for the loop L1 above.

Part B) Provide the loop equation for the loop L2 above.

Part C) Provide the loop equation for the loop L3 above.

Part D) Provide an expression for the net current flowing into the node labeled 'A' above.

Part E) Find the values of I1, I2, and I3. Which, if any, currents were flowing in the opposite direction to that originally indicated above? **Hint Use L1, L2, and node A to solve.

Part F) What is the power being provided by the 5V battery? Are either of the batteries being "charged"?

Part G) How much power is being dissipated the diagonal resistor R3?
