When coils A and B are utilised in parallel, the current drawn is:
Total resistance is 1/R = 1/Ra + 1/Rb = 1/24 + 1/24 = 2/24 = 1/12
R = 12 ohms
I = V/R = 220/12 = 18.33 amps
Two resistance coils A and B of 24 ohm resistance each are linked to a 220V supply line on an electric heater. These coils can be utilised in a series or parallel configuration. Calculate the current drawn in the following situation: coils A and B are used in parallel
