Solve

Answer 1

Explanation:

Given :

A conductor of 20 Ω resistance is connected across a 20 V battery

To find :

How much heat energy is produced in 10 minutes

Solution :

➸ H = l²RT

➸ H = V²/R x t

➸ H = 20²/20 x 600

➸ H = 400 x 600/20

➸ H = 20 x 600

➸ H = 12000 Joules

∴ 12000 joule heat energy is produced in 10 minutes

Answer 2

$\huge\underline\mathfrak{\pink{A}\blue{N}\purple{S}\orange{W}\red{E}\green{R}}$

Given :

• R = 20
• V = 20V
• T = 10min

To find:

• H (heat energy produced in 10 minutes).

Solution:

H = I²RT

=> H = V²/R × T

=> H = 20²/20 × (10×60sec)

=> H = 400/20×600

=> H = (20 × 600)joules

=> H= 12000 joules

Hence, the heat energy produced in 10 minutes :

= 12000 joules
