What Is The Relationship Between Voltage And Current

For simplicity think of it as the number of electrons flowing through the circuit per second.

What is the relationship between voltage and current. The basic difference between voltage and current is that voltage is the amount of energy per charge which is required to move electrons from one point to another while current is the rate of flow of charges. Relationship between voltage and current. That is if the voltage doubles the current doubles too. Relationship between energy transferred current voltage and time the potential difference or voltage v across two points is defined as the energy e dissipated or transferred by a coulomb of charge q that moves through the two points.

Current and voltage are two fundamental quantities in electricity voltage is the cause and current is the effect. Therefore potential difference current is the rate of charge flow. This means that if the voltage is high the current is high and if the voltage is low the current is low. The relationship between the voltage across a resistor and the current through that resistor is linear.

Relationship between voltage and current is described in the equation of ohm s law v ir. Current is the flow of electrons flowing through a circuit. 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. It s measured in amperes and is not really the number of electrons but proportional to the.

The relationship between voltage current and resistance forms the basis of ohm s law. The voltage between two points is equal to the electrical potential difference between those points.
