Electricity and Electronics – ‘I Can’ Statements
I Can:
 recall the meaning of electrical symbols and the function of each component
 state the meaning of the terms current (symbol I) and voltage (symbol V)
 state that the unit of current is the ampere or amp (symbol A)
 state that the unit of voltage is the volt (symbol V)
 draw a circuit using the correct symbols and place an ammeter in series and
voltmeters in parallel with the components
 explain that as the resistance in a circuit increases the current flowing in the
circuit decreases
 state that resistance (symbol R) is measured in ohms (symbol Ω)
 determine the resistance of resistors using the resistor colour code
 build a series circuit and measure the current flowing in the circuit using an
ammeter
