Consider the following circuit with R1 = 1Ω, R2 = 2Ω, R3 = 3Ω, R4 = 4Ω and I4 = 3A. The emf of the battery on the right is 20V and the emf of the battery on the left is unknown.

Determine the following:
the current through each of the other resistors,
the voltage of the battery on the left
the power delivered to the circuit by the battery on the right
