Question

an electric toaster of resistance 80 ohm takes a current of 10A. calculate the heat developed in 2 minuestes?

Answer 1

Answer:

hey here is ur answr

Explanation:

so now here resistance r=80 ohm

current =10A

so apply ohms law

thus V=IR

So then substitute resistance and current ka values in it

thus v=800V

so apply

H=VIt

so then heat=800×10×2

so now H=16000 joules

this is your answer

I hope now u understand how to crack such numericals
