Asked by Radhika
A hot plate of an electric oven connected to a 220V line has two resistance coils A and B, each of 24 ohms resistance, which may be used separately, in series, or in parallel. What are the currents in the cases?

In series the R is 24 ohms (R1 + R2).
In parallel the R is 12 ohms(1/R1 + 1/R2 = 1/R).
E = IR or I = E/R. You know E and R, solve for I.
In parallel the R is 12 ohms(1/R1 + 1/R2 = 1/R).
E = IR or I = E/R. You know E and R, solve for I.
