Es - a measure of the force that moves charges though a conducting material is
2
amperes
insulation
o
resistance.
d)
voltage.

D) Voltage

Explanation:

First of all, we need to clarify that voltage is not really a force as it is defined in physics (in fact, it is not measured in Newtons). However, voltage refers to the potential difference between two parts of an electric circuit, and this potential difference is what makes the charge carriers moving through the circuit.

In fact, let's consider an electron moving through a circuit. The electron moves only if there is an electric field (and so, if it experiences an electric force) - this means that there must be a potential difference, and the electron moves from the point at lower potential to the point at higher potential. In this sense, the voltage acts as a "force" that pushes the electrons (for this reason, it is also called electromotive force, e.m.f.)

The other options are wrong because:

- Ampere is the SI unit for the current

- Insulation indicates a material that does not allow current to pass through

- Resistance is a quantity indicating how much a material opposes to the flow of charge

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
