Solving a circuit with series and parallel resistors Finding currents and voltages (pure circuits) The relationship is written as. This article was co-authored by Ralph Childers. Donate or volunteer today! 5 = R (0.01) If the problem only tells you to fill out a circuit diagram, use the method above to find resistance, voltage, and current. Caleb Smith. University of South Alabama. On a circuit diagram, a resistor looks like a zig-zag in the wire. Solution to Example 1 Solve for I1 Ohm's Law works with values in the same row. Ralph Childers is a master electrician based in the Portland, Oregon area with over 30 years of conducting and teaching electrical work.

You know the values of V and R for the light bulb, so you can use Ohm's Law to solve for the current: I = 80V / 100Ω = 0.8 A (amps) Because the current is the same anywhere on a series circuit, the answer is 0.8 amps.
