1. For the circuit below use mesh analysis (no other method is permitted) to solve for the loop currents. Find the voltages across the resistors and also the power dissipated by each resistor. Then put your answers in table 1. (30 Points) R1 10 k Ohm R2 30 k Ohm RS 15 k Ohm E1 ?? R4 5 k Ohm R3 20 k Ohm TABLE 1 VRs PR1- PR2- PR3- PRA PRs- 12 = VR1 VR2 =
