UNIT 1 - Electric circuits● Draw the symbols of components used in electrical circuits
● Describe the pattern in current and voltage in both series and parallel circuits
● Describe how to measure the voltage across and current in electrical
components in electrical circuits
● Spec prac: Investigate how current changes with voltage for a component
● Use the equation ( I = V/R)
● Describe how adding components in series and parallel changes the total
resistance in a circuit
● Calculate total resistance and total current in a series circuit
● HT only: Calculate resistance and current in a parallel circuit and circuits
consisting of combinations of series and parallel connections,
● Use the equation: power = voltage x current
● HT only: Use the equation: power = current2 x resistance
● Explain the design and use of circuits to explore the variation of resistance
