Question

An electric iron of resistance 20 takes and current of 5 ampere calculate the heat developed in 5 second

Answer 1

Answer: R = 20 ohm

               I =5 A

               T= 5 Sec.

               H=I^2 RT

               H = 5 X 5 X 20 X 5

               H = 25 X 100

               H = 2500 J ( Answer)

Explanation:

Answer 2

Answer:

GIVEN,

i=5 AMPERE

r=20 OHM

t=5 SECOND

THEREFORE USING FORMULA

$h = {i}^{2} rt$

$h = {5}^{2} \times 20 \times 5$

$h = 2500 \: </em></strong><strong><em>j</em></strong><strong><em>o</em></strong><strong><em>u</em></strong><strong><em>l</em></strong><strong><em>e</em></strong><strong><em>$
