Electricity and Energy s and Revision from S1 and S2 s I am aware of different forms of energy and can name some I can state the energy changes which take place in everyday pieces of equipment I am aware of current and voltage in a circuit I can identify a range of circuit symbols I can recognise series and parallel circuits Measure current in a circuit Measure voltage in a circuit Explain how a V de G stores charge Set up a series circuit Set up a parallel circuit Identify energy changers that convert electrical energy to other forms of energy Identify an energy changer which converts kinetic energy to electrical Explain what happens if a lamp in a circuit is unscrewed Resistance I can measure current, voltage and resistance using appropriate meters in series or parallel circuits. I can state the factors that affect resistance. I can use the appropriate relationships between voltage, current and resistance in calculations for series circuits. Measure resistance of individual resistors and combinations of resistors (both series and parallel) using an ohmmeter Carry out a fair experiment to compare the factors which affect resistance Explain the effect of temperature on resistance Carry out an experiment based on Ohm s Law and write up the experiment as an LO1
