Question

The product of charge through, and potential across, an electrical device is:

Answer 1

The option is Work.

The product of charge and potential is equal to the energy. Adn, as we know work is related to energy as the capacity to do work.  

Alos, because, Potential is given as, V = E/q
or E = Vq
Thus, the product of charge through, and potential across, an electrical device is:work
  

Answer 2

Answer:

The product of the charge and voltage is the work .

Explanation:

According to Ohm's law

The voltage is equal to the product of the current and resistance. Its unit is volt.

$V= I\times R$

Power :

Power is the defined as the electric energy per unit time. its unit is J/s or watt.

$P=\dfrac{E}{t}$

According to Ohm's law,

The power is equal to the square of voltage divided by the resistance.

$P=\dfrac{V^2}{R}$

The power equal to the product of resistance and square of current.

$P = R\times I^2$

The product of current and voltage is equal to the power.

$P=I\times V$

Current :

The current is equal to the voltage divided by the resistance.

The ampere is the unit of current.

Work : Work is related to the energy.

The Voltage is equal to the energy divided by the charge.

$V=\dfrac{E}{q}$

The product of charge and potential is called energy.

$E=q\times V$

Hence, The product of the charge and voltage is the work .
