Why are decorative lights for Christmas trees connected in parallel and not series? Why does adding additional lamps in series, make them all dimmer? Current through, and potential difference across, each lamp can be measured to get numerical values and see the effect of adding more lamps. 6.2.2 Properties of series circuits and adding resistors in series. For components connected in series: there is the same current through each component the total potential difference of the power supply is shared between the components. the total resistance of two components is the sum of the resistance of each component. resistance, R, in ohms, Ω 1 Explain why the current through each component in a series circuit is the same. Why does adding more lamps in series cause the current to decrease? What is resistance? Describe how the potential difference of the power supply is shared between the components and that the share of the potential difference a component receives depends on the resistance of that component. Calculate the resistance or two components in a circuit Investigate series circuits to find out how adding resistance, in the form of a variable resistor, changes the current and the potential difference.
