Question

a current of 0.2 ampere flows through a wire whose end are a potential difference of 15 volt calculate the resistance of wire and the heat energy produced in one minute​

Answer 1

Answer:

Resistance of wire is 75 ohm

Heat produced in one minute is 180 Joule

Answer 2

Answer:

from ohm's law V=IR

15=0.2R

R=75 ohm

from joule's law heat produced=i^2 R t=0.2*0.2*75*60   (t=1min=60 sec)                                                      

H=180 j.
