Which statement accurately describes how electrical power and voltage are
related?
A. Power decreases as voltage increases.
B. Power is always half the amount of voltage.
C. Power is always twice the amount of voltage.
D. Power increases as voltage increases.

Respuesta :

Answer: B

Explanation:

According to Ohm's Law, the answer is B.

Ohm's Law states that power is equal to volume x current.

If volume x current equals power, that means they are both 50% of power.

Ohm's Law:

power = voltage x current

current = voltage x power

voltage = power x current

I hope this answer helped.

Power is always half the amount of voltage. Hence, option B is correct.

What is voltage?

Voltage is the potential difference between two points in a circuit or the electromotive force in a given circuit and is expressed in volts (V).

Voltage is measured by a device called a voltmeter that is always connected in parallel with the current source.

When voltage is measured between two points on a wire in a circuit with zero or no resistance in between the two points then the voltage will be zero.

From the ohm's Law, voltage is given the product of resistance and current and thus if the resistance is zero then the voltage will be zero.

Ohm's Law states that power is equal to volume x current.

If volume x current equals power, that means they are both 50% of power.

Ohm's Law:

power = voltage x current

current = voltage x power

voltage = power x current
