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
