Two conducting wires of same material and equal lengths and diameters are first connected in series and then parallel in a given circuit. Calculate the ratio of heat produced in series and paralle combination?

Expert Answer:

Heat produced, H = I2 Rt,
where I = current, R = resistance, t = time
 
H is proportional to R;
 
The ratio of values of resistances in series and parallel connection is 2 : (1/2) = 4 : 1
 
So, the ratio of heat produced in series and paralle combination = 4 : 1
