Which statement describes how electrical power is calculated?

D. Power is the product of voltage and current.

Explanation:

Electrical power is derived from the product of current and voltage;

  Power  = current x voltage  = I V

I is the current

V is the voltage

R is the resistance

Now;

   V = IR;

     So;

  Power  = I x (IR) = I²R

Also,

   Power  =  

The right choice is D

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
