Give an explaination to the following formula p=I^2R
1 answer:
Answer:
Explanation:
This is the equation that defines the power consumed by an electrical circuit. It is normally defined as the product of the voltage applied (V) times the current (I) that runs through it. And in the case of a resistive circuit (resistors in the circuit totaling a certain resistance R), one can use Ohm's law to replace the voltage by the product of the current (I) times the resistance (R), obtaining then the square of the current:

Answer:
The work done by a particle from x = 0 to x = 2 m is 20 J.
Explanation:
A force on a particle depends on position constrained to move along the x-axis, is given by,
We need to find the work done on a particle that moves from x = 0.00 m to x = 2.00 m.
We know that the work done by a particle is given by the formula as follows :
So, the work done by a particle from x = 0 to x = 2 m is 20 J. Hence, this is the required solution.
