Case (i): When each coil is used separately

Here, Potential difference, V = 220 V

Resistance of a coil, R = 24 Using Ohm’s Law, the current passing through one coil is given as, Case (ii) Calculation of current when the two coils are connected in series

When the two coils of 24 each are connected in series, then their combined resistance will be R= 24 + 24 = 48 Potential difference, V = 220 V

And, Resistance, R = 48 Q

Again, Current passing through both coils connected in series, is given as: Case (iii) Calculation of current when the two coils are connected in parallel

When the two coils of 24 each are connected in parallel, then their combined resistance will be given as: Here, Potential difference, V = 220 V

Resistance of two coils in parallel connection, R = 12 (Two coils in parallel)

Now, Current, I = Rate this question :
