How does the heat
Asked by fathima12 | 08 Oct, 2010, 09:26: PM
answered-by-expert Expert Answer
Heat before putting in series (by each of the wire individually): V2/R
 
In series, effective resistance = R + R = 2R
When put across the same potential difference V, heat generated = V2/2R
 
Heat generated becomes half when put in series combination as compared when only one of them was used.
