Answer
Given:
A resistor produces 200 J of heat every second
Connected with a source of 220 Volts
To Find:
It's Resistance and the Current
Solution:
We know that,
When, Work is dissipated in the form of Heat.
H = W
Therefore,
Given that,
H = 200 Joules
V = 220 Volts
t = 1 second
According to the Question,
We are asked to find it's Resistance
Therefore,
Substituting above values,
We get,
According to the Question,
We are also asked to find the current that will pass through it
Hence,
Using Ohm's Law
To find current ()
Given that,
V = 220 Volts
And, We found out that,
R = 242 Ω
Substituting above values,
We get,
