Voltage attempts to make a current flow, and current will flow if the circuit is complete. Voltage is sometimes described as the 'push' or 'force' of the electricity, it isn't really a force but this may help you to imagine what is happening. It is possible to have voltage without current, but current cannot flow...While voltage can exist without the current, the current cannot flow without the voltage as it is the effect of voltage and this is the biggest difference between the two.Voltage-Current Graph for a Metal Conductor When metals are heated it causes the atoms in the metal to vibrate more.

Relationship Between Voltage and Current

Current and voltage are two basic amounts in electrical energy. Voltage is the purpose and present is the impact.

The voltage between two issues is equal to the electrical potential distinction between the ones issues. It is in truth the electromotive drive (emf), accountable for the movement of electrons (electric current) via a circuit. A flow of electrons compelled into movement via voltage is current. Voltage represents the possibility of every Coulomb of electric rate to do paintings.

The following video explains the connection between voltage and current:

Circuit

An electric circuit with a voltage source (e.g. a battery) and a resistor.

A voltage source has two issues that have a difference in electric possible. When there is a closed loop path between those two points, it is called a circuit and present can go with the flow. In the absence of a circuit, present will not drift although there is voltage.

Symbols and Units

An uppercase italic letter I symbolizes current. The usual unit is Ampere (or Amps), symbolized by means of A. The SI unit for current is Coulomb/2d.

1 ampere = 1 coulomb/2nd.

One ampere of present represents one coulomb of electrical charge (6.24 x 1018 rate carriers) shifting previous a selected point within the circuit in a single second. The instrument used to measure present is named an Ammeter.

An uppercase italic letter V symbolizes voltage.

1 volt = 1 joule/coulomb.

One volt will force one coulomb (6.24 x 1018) fee carriers, reminiscent of electrons, via a resistance of 1 ohm in one second. The Voltmeter is used to measure voltage.

Fields and Intensity

An electrical current all the time produces a magnetic field. The stronger the current, the more intense is the magnetic field.

A voltage produces an electrostatic field. As the voltage will increase between two points the electrostatic field turns into more intense. As the gap increases between two issues having a given voltage with appreciate to one another, the electrostatic depth decreases between the points.

Series and Parallel connections

In a sequence circuit

Voltages upload up for elements hooked up in collection. Currents are the similar via all components attached in series.

Electrical elements in a chain connection

For instance if a 2V battery and a 6V battery are connected to a resistor and LED in series, the current through all of the parts can be similar (say, 15mA) but the voltages can be other (5V around the resistor and the 3V across the LED). These voltages add as much as the battery voltage: 2V + 6V = 5V + 3V.

In a parallel circuit

Currents upload up for components attached in parallel. Voltages are the similar thru all components hooked up in parallel.

Electrical components in a parallel connection

For example if the similar batteries are attached to a resistor and LED in parallel, the voltage throughout the elements will be the same (8V). However, the 40mA current throughout the battery is shipped over the 2 paths in the circuit and get broken all the way down to 15mA and 25mA.
