Question

TWO CONDUCTING WIRE OF THE SAME MATERIAL AND OF EQUAL LENGTH AND EQUAL DIAMETER ARE FIRST CONNECTED IN SERIES AND THEN PARALLEL IN A CIRCUIT ACROSS THE SAME POTENTIAL DEFFERENCE THE RATIO OF HEAT PRODUCED IN SERIES AND PARALLEL COMBINATION WOULD BE ? A)1:2 B)2:1 C) 1:4 D) 4:1 PLEASE TELL EXPLANATION ALSO​

Answer 1

(V/2R)/(V/(R/2)) = (1/4) = 1:4

Apply, V = IR

V is same for both cases.

R for series = 2R

R for parallel = R/2
