Question

A hot plate of an electric oven connected to a 220 V line has 2
separate resistance coils A and B each of resistance 11ohm, which may be used in series or in parallel. If all the electrical energy supplied is used up in heating, find the amount of heat produced in the circuit when it is used in series and in parallel.​

Answer 1

can't understand anything

Answer 2

Answer:

resistance 110.h will be 13 cm each so it would be 15.78 ohm
