What is relation between current and voltage?
The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
How do you explain current and voltage?
Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).
What is voltage and current with example?
Note: 1 Volt= 1 Joule/coulomb. The SI unit of current is Ampere (A). Note: 1 Ampere = 1 coulomb/second. Voltage is denoted by “V”….Related Articles:

What comes first voltage or current?
Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. In other words, voltage is the “energy per unit charge”. Current is the effect (voltage being the cause). Current cannot flow without Voltage.
What is difference between voltage and current?
Voltage is the potential difference between two points in an electric field, which causes current to flow in the circuit. Current is the rate of flow of electrons is called current. Voltage is the cause of current (being an effect). Current is the effect caused by Voltage.
What is voltage exactly?
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).
Can current exist without voltage?
Voltage is the Cause, Current is the Effect Voltage attempts to make a current flow, and current will flow if the circuit is complete. It is possible to have voltage without current, but current cannot flow without voltage.
What is the relationship between current and voltage?
Current and voltage are two fundamental quantities in electricity. Voltage is the cause and current is the effect. The voltage between two points is equal to the electrical potential difference between those points.
What exactly is current and voltage?
Current is the rate at which the electric charge flows past a point in a circuit, while the voltage is the difference in charge potential between two points in an electric field . The unit of current is the ampere, while that of the voltage is the volt.
Does voltage always cause current?
Voltage, as an expression of potential energy, is always relative between two locations, or points. Sometimes it is called a voltage “drop.” When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current .
What does voltage current mean?
Voltage is the electrical force that would drive an electric current between two points . Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.
