Which Statement Accurately Describes How Voltage And Electrical Power Are Related class=

Sagot :

Voltage is always twice the amount of power. This is statement is accurately describe the relationship between voltage and electric power.

What is Power?

Power is defined as amount of energy transferred or converted per unit time.

From power-current relation

P=VI

Also, From Ohm's Law we know that,

V= IR

Replacing the value of V in the above equation,

[tex]P =\frac{I^{2} }{R}[/tex]

When the values for current and resistance are given then the equation is,

[tex]P =\frac{V^{2} }{R}[/tex]

Hence , Voltage is twice to the electric Power.
