Answer 2

Answer:

E = V × Q

where:

E is the energy transferred in joules, J

V is the potential difference in volts, V

Q is the charge in coulombs, C

This equation can be rearranged to V = E ÷ Q

So voltage is energy transferred divided by charge.

The rearranged formula means we can define one volt as one joule per coulomb.

In any electrical appliance their is a simple relationship between the power output of a component, the potential difference across that component, and the current running through it.

This is because charge times potential difference is energy, so (charge per unit time) times (potential difference) gives (energy per unit time).

Thus,

we have P=VI.
