How much electrical energy is required to move 4.00 mC of charge through a potential difference of 36.0 V?
SameAsMuli
0.144 JOULES. One can calculate this from the formula E=Vq in which E is energy, V is potential difference & q is charge.

What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
Why does an electrical current not go through a power worker when he is working on power lines?
You are presumably describing those linesmen who work on live transmission lines while being suspended or while sitting on helicopters? For current to pass through the body, there must be a difference in potential across different parts of the body. If (just like a bird) a linesman is connected to a line conductor, his body assumes the same potential as that line -no potential difference, no current.
One volt is equal to?
One volt is the electric potential required to generate one ampere through one ohm. One volt is the electric potential involved when one ampere generates one watt of power. One volt is one joule per coulomb.
How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
WHAT IS CURRENT AND AMPERE VOLTAGE?
Amperage is the measure of electrical current, which is the measure of the electron flow through something (like a wire). The more electrons that flow through the wire, the higher the amperage. Current is understood as moving from higher voltage to lower voltage but since electrons are negatively charged, they actually flow in the opposite direction.Voltage is a measure of electrical potential between two items. The electrical potential can be looked at as the difference in the electrical charge between two items. The item with more negatively charged electrons has a lower voltage.
What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
What is required for current to flow through an electrical current?
Potential Source connected across a Closed Circuit Path.
What is the difference between resistor and resistance?

A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors

Volts are a measure of what characteristic of electricity?
Volts are a measure of the potential difference or electrical pressure in a circuit. It represents the force that drives the flow of electricity through a conductor.
If there are 2 points with different potential energy will there still be an electrical current through the circuit?
Not necessarily. The two points with potential difference, will have to be connected via a conductor, for current to flow.Provided that a circuit exists, then current WILL flow.
What is the role of a dry cell in a torch?
To provide the electric potential difference required to get a current flowing through the bulb and the torch to produce light.
The potential is constant through a given region of space Is the electrical field zero or non zero?
the electrical
How can electric potential be high when electrical potential energy is realitively low?
Electric potential can be high when electrical potential energy is relatively low if the charge is low as well. ... It is correct to say that an object with twice the electric potential of another has twice the electrical potential energy only if the charges are the same.
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
What is the definition of electrical energy?
electrical energy - energy made available by the flow of electric charge through a conductor;
How does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
