Unformatted text preview: Ohm ’ s law, if we inspect this more closely, we are defining currents. V = IR, rearranging this equation, we get: V/R = I Thus, if there were a current source in the circuit, we would simply add the value to the equation. c) If we solve the function above, we find that v1 = 40V. Knowing the voltage at the node, and knowing that parallel resistors share the same voltage drop, we can simply use Ohm ’ s law to determine the currents through each branch. V = I *R 40 = I * 80 Ω 40 = I * 20 Ω b) I 80 Ω = .5A a) I 20 Ω = 2A...
