Question

14. 100 J of heat is produced each second in a 412
resistance. The potential difference across the resistor
is
(a) 20 V
(b) 10 V
(c) 5 V
(d) 15 V​

Answer 1

Answer:

its a 20 V

Explanation:

Q=100J , R=4Ω , t=1s , V=? Thus, the potential difference across the resistor is 20V . Additional Information: The heat produced by the resistor is known as Joule Heating.
