Lesson outcome
I can use the rules for current and potential difference and the equation I = V ÷ R to analyse parallel circuits.
Show transcript
Current can be calculated using the equation: current = p.d. ÷ resistance (I = V ÷ R).
The rules of current and p.d. for a parallel circuit can be applied to find some missing values of current and p.d.
The equation I = V ÷ R can be rearranged so that either p.d. or R is the subject of the equation.
If any two values in the equation I = V ÷ R are known, the third can be calculated.
If only one value in I = V ÷ R is shown for a component, circuit rules need to be applied to the rest of the circuit.
