For DC: power (in watts) = current (in ampere) x voltage (in volts).
Energy = power x time, so energy = current x voltage x time (time in seconds).
For AC, a power factor may have to be included (the cosine of the angular displacement between current and voltage). This is often near one, but it may be less.

∙ 12y agoBy definition, an electric circuit allows electric current to flow from a source of current and back around to that source in a complete circuit, rather like water from a pump outlet flowing round a pipe back to the pump inlet in a circulating system. The electric current may flow in only one direction at all times (direct current, or pumping in only one direction) or may change direction periodically (alternating current, or reversing the pump periodically).

What is the the energy carried by each unit of a current called?
Amperage is the energy carried by each unit of a current
What else increases as energy carried by a current increases?
The amount of electric energy that is converted into thermal energy increases as the resistance of wire increases. As the resistance in the current increases, the current in the circuit decreases.
What type of energy is carried by moving negative charges?
That is the electric energy. It is called the electricity
How is sound energy carried?
Sound energy is carried from the music thingy to our ears
What type of energy is carried by light?
light energy
What is the the energy carried by each unit of a current called?
Amperage is the energy carried by each unit of a current
What does the energy carried by an electric current depend on?
The energy carried by an electric current depends on a conductor in order to flow. an Insulator disrupts the flow

How does the energy carried in a sound wave and the energy in a moving ball?
Energy carried in a sound wave is all around us but energy carried in a ball is causing friction within the ball which is giving it energy
Is alternating current can be stored?
"Current" cannot be stored at all in any way; when you stop it moving, it isn't current any more and moving it means using it. The energy carried however, can be stored in several different ways.
Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
Can the amount of energy carried by a power line be increased by raising voltage?
Yes, by increasing the voltage in a power line, the amount of energy carried can be increased. This is because power (P) is the product of voltage (V) and current (I), and increasing the voltage while keeping the current constant will result in higher power carrying capacity. However, it is important to consider the limitations of the equipment and the safety considerations when increasing voltage levels.
What is carried by an electric current?
Electric
What energy is carried on waved by vibrations?
sound energy
