Question

two resistance are first connected in series then in parallel find the ratio of heat produced in series and parallel​

Answer 1

Answer:

Heat produced in the circuit is inversely proportional to the resistance R.

Let RS be the equivalent resistances of the wires if connected in series and RP be the equivalent resistances of the wires if connected in parallel

Then RS =R+R=2R

And1/ RP = 1/R +1/R

1/ RP = 2/R

Or RP =R/2

Now the ratio of heat produced is given by

= 1/4

Explanation:

ratio is 1 is to 4
