Question

find heat dissipated across resistor when current 5 ampere passes through it for 1 minute which has resistance 1 ohm

Answer 1

Answer:

Electric current = 5 A

time = 60 sec

Resistance =

${i}^{2} rt$

25*1*60 = 2000 joule

Given ,

Current ( I ) = 5 amp

Resistance ( R ) = 1 ohm

Time ( T ) = 1 min = 60 sec

$\large\fbox{ \fbox{ \bold{Heat = {(I )}^{2} × R × T }}}$

$\to$ Heat = ( 5 )² × 1 × 60

$\to$ Heat = 25 × 60

$\to$ Heat = 1500 Joule
