Question

A Resistance of 12ohm is connected to a battery of 10 v. The heat energy in joules jenerated per minute is?

Answer 1

Given:

A Resistance of 12ohm is connected to a battery of 10 V.

To find:

Heat generated (in Joules)

Calculation:

Power delivered due to current flow through the resistor

$\sf{ = \dfrac{ {(voltage)}^{2} }{resistance} }$

$\sf{ = \dfrac{ {(10)}^{2} }{12} }$

$\sf{ = \dfrac{ 100}{12} }$

$\sf{ = 8.33 \: watt }$

Now , the heat generated in a specified time will be the product of power delivered and the time.

$\rm{heat = power \times time}$

$= > \rm{heat =( 8.33 \: watt)\times (60 \: sec)}$

$= > \rm{heat =500 \: joule}$

So, final answer is:

$\boxed{ \bf{heat \: generated =500 \: joule}}$

Hope It Helps.

Answer 2

500 Joules is the Answer.
