Question

Explain Energy dissipation in a reeistance?
Please answer it correctly. I will brainlist

Answer 1

Answer:

Whenever there is a change in a system, energy is transferred and some of that energy is dissipated . Dissipation is a term that is often used to describe ways in which energy is wasted. Any energy that is not transferred to useful energy stores is said to be wasted because it is lost to the surroundings.

Answer 2

Energy dissipation in resistors

As a charge q moves through a resistor, it loses a potential energy qV where V is the potential drop across the resistor. This energy goes into heat, much like the way a ball of putty that falls off a cliff converts its potential energy to heat when it hits the ground. We refer to this conversion of potential energy into heat as dissipation.

The power dissipated in a resistor is the energy dissipated per time. If an amount of charge Dq moves through the resistor in a time Dt, the power loss is P = d W d t = I V = I 2 R = V 2 R .

where I is the current through the resistor and V is the voltage drop across it.

The formula P = I V also gives the power generated by a battery if I is the current coming from the battery and V is its voltage.
