An electromotive force is the potential difference developed by a voltage source, and is necessary to cause current to flow through a circuit. Strictly-speaking, it is the open-circuit potential difference of a battery, generator, etc. An alternative definition is that an e.m.f. is equal to the sum of the voltage drops around any closed loop, including any internal voltage drop.

What causes current flow-emf?
Current flow in a circuit is driven by electromotive force (emf), which is generated by sources such as batteries or generators. Emf creates a potential difference between two points in the circuit, causing electrons to move through the conductive material. This movement of charge constitutes electric current. Factors like resistance also play a role in determining the amount of current that flows for a given emf.

What process by which an electric current is produced?
An electric current is produced through a process called electromotive force (EMF), which can be generated by batteries, generators, or solar cells. When a circuit is closed, the EMF causes the flow of electric charge, resulting in an electric current.

What is emf in physics?
EMF, or electromotive force, is a measure of the energy provided by a source (such as a battery) to move a unit charge around a closed circuit. It is responsible for driving the flow of electric current in a circuit. EMF is measured in volts.

What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.
What is the function of the voltmeter in an electric circuit?
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
The function of a capacitorin an electric circuit is to?
The function of a capacitor or an electric circuit is to store energy. It keeps this energy stored until it is need for release at a later time.
What is meant by electro-motive force?
Electro-motive force (EMF) is a measure of the electrical energy provided by a voltage source to drive current in a circuit. It is the force that pushes electrons through a circuit, creating a flow of electric charge. EMF is typically measured in volts.

What are the differences between potential difference and emf?
Potential difference is the difference in electric potential energy between two points in a circuit, while electromotive force (emf) is the total energy provided per unit charge by a battery or voltage source. In other words, potential difference measures the voltage drop across a component in a circuit, while emf represents the energy per unit charge supplied by the source.
