Two resistance `R_(1) and R_(2)` may be connected either in series or in parallel across a battery of zero internal resistance. It is required that the joule heating for the parallel combination be five times that for series combination if `R_(1)` is `100 Omega` find `R_(2)`.

Two resistance R_(1) and R_(2) may be connected either in series or in parallel across a battery of zero internal resistance. It is required that the joule heating for the parallel combination be five times that for series combination. If R_(1) is 10Omega find R_(2) .

(a) Two heater coils made of the same material are connected in paralled across the mains. The length of diameter of one the coil is triple that of other. Which of these will produce more heat? (b) Three equal resistors connected in series across a source of emf together dissipated 10 Watt of power. What would be the power disspated if the same resistors are connected in parallel across the same source of emf? Two resistor R_(1) and R_(2) may be connect either in series or in parellel across a battery of zero internal resistance. it is required that joule heating for the parallel combination be four times than for series combination. if R_(1)= 100 Omega find R_(2) (d) The three resistance A, B and C have values 3R, 6R and R respectively.
