Question

A conductor of 20  resistance is connected across a 20 V battery. How much heat energy is produced in 10 minutes? solve fast plz..

Answer 1

Given :

• R = 20 ohms
• Potential Difference = 20 V
• Time = 10mins = 600 s

Solution :

⇒H = I²RT

⇒H = V²/R * t

⇒H = 20²/20 * 600

⇒H = 400 * 600/20

⇒H = 20 * 600

⇒H = 12000 Joules

Answer 2

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
