Two conducting wires of the same materlal and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in serles and parallel combinations would be-
P
(a) \( 1: 2 \)
(b) \( 2: 1 \)
(c) \( 1: 4 \)
(d) \( 4: 1 \)
