Question

A wire having 8ohm for registence
produces 18 j of heat if current
flows in wire for 10 sec then
find the amount of currenta wire having 8ohm of registance produce 180 joule of heat if current flow in wire for 10 seconds then find the amount of current ​

Answer 1

Answer:

please mark me as brain least

Explanation:

For 3Ω resistance heat =

R

V

2

=12J

V

2

=12×R=36

V=

36

For upper branch in parallel combination

R

net

=6Ω,V=6V

i=

R

V

=

6

6

=1A

Heat produced in 4Ω

P=H=L

2

R=1

2

(4)=4J
