Question

Calculate the thermal energy produced in the heater after 10 minutes. Given that :12 volt and 6.0 ohm

Answer 1

Explanation:

Given,

Voltage= 12V

Resistance= 6 Ohm

Time= 10min = 10*60

=600 Sec

By Ohms Rule,

V= IR

I= V/R

I= 12/6

I= 2A

Therefore, Current= 2 Ampere

Thereafter, Thermal Energy= I^2RT

${2}^{2} \times 6 \times 600$

$= 4 \times 6 \times 600$

$= 14400j$

Therefore, 14400J of energy is produced by the Heater

I Hope this will Help!!!!!!
