Compare and contrast electric potential energy and electric potential difference? Explain.
forsale [732]

Answer:

<u><em>Electric Potential Energy:</em></u>

The energy that is needed to move a charge against an electric firld is called Electric Potential Energy

<u><em>Electric Potential Difference:</em></u>

The amount of work done in carrying a unit charge from one point to an other in an electric field is called Electric Potential Difference.

<u><em>Relation:</em></u>

Relation between Electric potential and electrical potential energy is given by

\delta V=\frac{PE}{q}

Here PE represents Electric potential energy

and \delta V is Electric potential difference

it means electric potential difference is the difference in electric potential energy divided by the charge.

An electric furnace that draws 40 amps with an applied voltage of 240 V will consume ________ watts.
irinina [24]

The electric furnace will consume 9600 watt of power.

To find the answer, we need to know about the electric power.

<h3>What's the electric power?</h3>
  • Electric power is defined as the product of voltage and current.
  • Mathematically, power= V×I
  • Its si unit is watt.
<h3>What will be the power consumed by an electric furnace that draws 40A with an applied voltage of 240V?</h3>

The power = 240×40 = 9600 watt

Thus, we can conclude that the power consumption of the electric furnace is 9600 watt.
