3 equal resistors connected in series across a source of e.m.f together dissipitate 10 watt. if the same resistors are connected in parallel across the same e.m.f. then what will be the power dissipated ?

Expert Answer:

For series, 10 = V2/3R

For parallel, P = V2 /(R/3)

Solving, we get P = 90 W
