Question

0•5 electricity flows through a bulb having resistance 40 ohm ,find the follo
wing terms
A,potential difference between the ends of resistance
B,about of heat produced in a resistance in 5s

Answer 1

So....

Potential difference = i*r

V = 0.5*40

V = 20V

And.......

Heat = V*I*t

H = 20*0.5*5

H = 50 J
