The two most common sources of electromotive force are batteries and generators. Batteries convert chemical energy into electrical energy, while generators convert mechanical energy into electrical energy.
The most common light source is the incandescent light bulb. However, LED lights are becoming increasingly popular due to their energy efficiency and longer lifespan.
The two most common forces on Earth are gravity and electromagnetism. Gravity is the force that pulls objects toward each other, while electromagnetism is the force that acts between electrically charged particles.
The most common forces shown in a diagram are gravity, normal force, tension, friction, and applied force. These forces act on an object to influence its motion or determine its equilibrium.
The two most common forces are gravity and electromagnetism. Gravity is the force that attracts objects with mass towards each other, while electromagnetism is a fundamental force that causes electrically charged particles to attract or repel each other.
The most common source of energy used to produce electricity is fossil fuels, such as coal, natural gas, and oil. These fuels are burned to generate heat, which is then used to produce steam that drives turbines to generate electricity.
electromotive force, current, resistance, and power
Most likely, you are referring to the electromagnetic force. It is one of the four known forces in physics along with gravity, the weak force, and the strong force.

The most common form of muscle force production is the concentric contraction force.
Glucose is the most common energy source in cellular respiration.
The most common source of fluoride in daily life is toothpaste.
The most common source of electricity in Manitoba is 120/240 volts. This is the supply source for Manitoba homes.

Division is the usual source.
Chickens are the most common animal source of Campylobacter infection in humans. Campylobacter bacteria are found in the intestines of poultry, making it a common source of contamination in meat products.
Electromotive force (emf, ) is a term used to characterize electrical devices, such as voltaic cells, thermoelectric devices, electrical generators and transformers, and even resistors. For a given device, if an electric charge Q passes through that device, and gains an energy W, the net emf for that device is the energy gained per unit charge, or W/Q. This has SI units of volts, or joules per coulomb, and hence can be thought of as a voltage induced by the device in question. Since force has the SI unit of the Newton, "electromagnetic force" is a misnomer, but one that over time has resisted change. In most circuits current is driven by a so-called "source of emf", which usually is a voltaic cell (or battery, which consists of voltaic cells in series and/or in parallel) or the power company. For a voltaic cell the source of emf is the chemical reactions that occur at each of the electrode-electrolyte interfaces, so that a voltaic cell can be thought of as two "surface pumps" of atomic dimension. The reactions at the electrode-electrolyte interfaces provide the "seat" of emf for the voltaic cell. For the power company, the source of emf is electromagnetic induction, which is more extended than an atomic size, but nevertheless is confined to the power generation building, usually many miles from the user. Sources of electromotive force include electric generators (both alternating current and continuous current types), batteries, and thermocouples (in a heat gradient). Electromotive force is often denoted by or ℰ (script capital E). Electromotive force is measured in volts (in the International System of Units equal in amount to a joule per coulomb of electric charge). Electromotive force in electrostatic units is the statvolt (in the centimeter gram second system of units equal in amount to an erg per electrostatic unit of charge).
