b) Complete the following table: A Comparison of Loads in Series and Parallel Series Parallel Current Io = I1 = I2 = I3 = I o = I1 + I2 + I3 + … Potential Difference (voltage) V o = V1 + V2 + V3 +… Ro = R1 + R2 + R3 Resistance V o = V1 = V2 =…. 1/R o = 1/R1 + 1/R2 + 1/R3 Diagram of circuit using one cell and two light bulbs 7. Calculate the current that flows through a resistor that is connected to a 5.0 volt cell and uses 500.0 J of energy in 10.0 seconds. E = IVt, I = E /Vt = 500.0/
