What Is The Relationship Among Electric Power Current And Voltage

Between a watt a kilowatt and a kilowatt hour which is a unit of power and which is a unit of energy.

What is the relationship among electric power current and voltage. Asked feb 19 2020. A watt is power a kilowatt is power and a kilowatt hour is energy. If 6 241 10 18 electrons move through a wire in 1 sec i e if these many electrons pass a given cross section of a wire during a 1 sec period the electric current is 1 amp 1 a. Voltage current and resistance.

The faster the water is flowing higher the pressure can be equated to voltage. It is the product of voltage and current. It is measured in watts. Regardless of what the voltage and current waveforms look like and regardless of the phase angle between them instantaneous power instantaneous voltage x instantaneous current when the unit for instantaneous voltage is volts and the unit.

In fact electric current is the rate of the electric charge of those electrons because we are concerned about the electric charge not the numbers corresponding to electrons. Voltages are generally expressed in volts with prefixes used to denote sub multiples of the voltage such as microvolts μv 10 6 v millivolts mv 10 3 v or kilovolts kv 10 3 v. This continuous movement of electric charge through the conductors of a circuit is called a current and it is often referred to in terms of flow just like the flow of a liquid through a hollow. The best analogy is a garden hose.

Voltage is electrical pressure e current is electrical flow i resistance is restriction of electrical flow r e i r. What is the relationship among electric power current and voltage. Solution for what is the relationship among electric power current and voltage. The voltage will be split evenly among the lamps though if a voltage of 6 v is impressed across the circuit in the preceding question and the voltage across the first lamp is 2 v what is the voltage across the second lamp.

Power is well electrical power. What is the relationship among electric power current and. Power is current times voltage. Think of power as total volume of water being pumped into a bucket.

Voltage is measured in volts with one volt being defined as the electrical pressure required to force an electrical current of one ampere through a resistance of one ohm. An electric circuit is formed when a conductive path is created to allow electric charge to continuously move.
