Two conducting wires of the same material and of equal length and equal diameters are first connected in series and then in parallel in an electric circuit. The ratio of the heat produced in series and parallel combinations would be :

Why is ammeter connected in series and voltmeter in parallel in the circuit?

Two heating wires of equal length are first con nected in series and then in parallel to a constant voltage source. The rate of heat produced in the two cases is

n equal resistors are first connected in series and then connected in parallel. What is the ratio of the maximum to the minimum resistance ?

Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in the two cases will be:

Two heater wires, made of the same material and having the same length and the same radius, are first connected in series and then in parallel to a constant potential difference. If the rate of heat produced in the two cases are Hs and Hp respectively then (Hs)/(Hp) will be
