Electromotive Force

Description

Electromotive Force (EMF) is a term used in physics to describe the electrical potential difference, or voltage, that is generated by a source such as a battery or generator. It is the driving force that pushes electrical charges within a circuit and causes current to flow.

Senses

1. Physics: The energy per unit charge that is provided by an electrical source to move the charge through a circuit.

Usages

Popular Usage: EMF is commonly used to refer to the voltage produced by a battery that is powering an electronic device.

Local Usage: In local communities, EMF is often discussed in relation to the potential health effects of electromagnetic fields.

Sample Sentences

Physics:

1. The electromotive force of the battery is 1.5 volts.
2. An increase in resistance can reduce the electromotive force in a circuit.

Popular Usage:

1. I need a new battery for my laptop as the electromotive force is too low.
2. The electromotive force of this power bank is 10,000 mAh.

Local Usage:

1. There is ongoing debate in the community about the possible health risks associated with high electromagnetic field (EMF) levels.
2. Some people choose to use EMF shielding devices to reduce their exposure to electromagnetic fields.
