Question

If a 10 ohm nichrome resistance coil is added to 12 volt battery and current source 30 minute then calculate the amount of heat produce​

Answer 1

Answer:

25920 joule

Explanation:

first of we know formula for hearing effect of electricity

H=i^2Rt

we also know i=v/R

i= 12/10= 1.2A

now putting the value of i in formula for H

we get.

H= 1.2×1.2×10×(30×60)

=(1440×18)joule

25920joules

check for calculation mistake
