Question

How long will it take a current of 0.5 amperes to produce 8.4kj of heat when flowing through a resistance of 100 ohms

Answer 1

Answer:

If current is represented as

′

i

′

resistance

′

r

′

and time

′

t

′

, then electrical energy e is defined

e=i

2

×r×t

(note- time in seconds=t×60)

e=2×2×100×1×60

=24000joule

We get, e=24000joule.
