Unformatted text preview: current, then your voltage drop is (iR) volts E1 = 2V, E2 = 3V r1 = r2 = 3.0 Ohm I = 1.0 mA (a) Find R (b) Find power dissipated in R (c) Find work per unit time done by each of the batteries R1 = R2 = 1 Ohm Find currents Analysis of Complex DC Circuits 1. Draw the circuit 2. Label all currents (one for each branch) 3. Designate a direction of current flow around all of the loops in your circuit (your choice is arbitrary) 4. Apply the Kirchhoff Junction Rule to reduce the number of unknown currents: The total current flowing into any branch point equals the total current flowing out of that branch point. 5. Apply the Kirchhoff Loop Rule to generate one equation for each loop you select: The sum of all voltage gains and drops around any closed loop in a circuit equals zero. R1 = R2 = 1 Ohm Find currents Dissipated power in a circuit! E1 = 2V, E2 = 3V r1 = r2 = 3.0 Ohm I = 1.0 mA (a) Find R (b) Find power dissipated in R (c) Find work per unit time done by each of the batteries...
