Question

b) 200 J of heat is produced in one second from a resistor of resistance 89. Find
the potential difference across the resistor and its power.
​

Answer 1

Answer:

Ans :133.417 v

$p = {v}^{2} \div r \\ 200 = {v}^{2} \div 89 \\ 200 \times 89 = {v}^{2} \\ {v}^{2} = 17800 \\ v = \sqrt{17800 } \\ v = 133.417$
