Current, Voltage and Resistance Apply the rules of current and voltage to to following circuits and use the V=IR equation to work out the missing currents, voltages and resistances as required. Unless stated otherwise, assume all bulbs are identical. DON’T FORGET YOUR UNITS! Remember: To work out resistors in series 1. A1 = _______ Resistors in parallel 5. A2 = _______ A1 = _______ V1 = _______ A2 = _______ V2 = _______ A3 = _______ V3 = _______ V1 = _______ V2 = _______ V3 = _______ 2. R1 = _______ A1 = _______ A2 = _______ V1 = _______ R1 = _______ 6. A1 = _______ A2 = _______ A3 = _______ 3. A1 = _______ V1 = _______ V1 = _______ V2 = _______ V2 = _______ R1 = _______ V3 = _______ R2 = _______ V4 = _______ 4. 7. A1 = _______ A1 = _______ A2 = _______ V1 = _______ A3 = _______ V2 = _______ 5. Calculate the resistance of: V1 = _______ The bulb = _________ V3 = _______ The resistor = __________ R1 = _______ V2 = _______
