Question

A cell is connected to a 9 ohm resistance because of which heat of 400j is produced per second due to current flowing through it obtain the potential difference applied accross the resistance.​

Answer 1

Answer: Potential difference applied across the resistance is 60 V.

Explanation:

Answer 2

Here, heat is given as 400 J per second.

Here, heat is given as 400 J per second.So, P= 400 J / 1 s

Here, heat is given as 400 J per second.So, P= 400 J / 1 sSuppose the equation used is P= V2/R, replacing the values you get

Here, heat is given as 400 J per second.So, P= 400 J / 1 sSuppose the equation used is P= V2/R, replacing the values you get400 = V2/9.

Here, heat is given as 400 J per second.So, P= 400 J / 1 sSuppose the equation used is P= V2/R, replacing the values you get400 = V2/9.Hence, V2= 400 x 9
