2.04 know and use the relationship between power, current and voltage: and apply the relationship to the selection of appropriate fuses
power (w) = current (A) x voltage (V)
when looking at a circuit a component will be given a power and a voltage appropriate to run at then the current can be calculated so the rating of the fuse can be selected for slightly higher than that.
