Voltages are produced by converting one form of energy into electrical energy. Mechanical energy can be converted into electrical energy (voltage and current) by moving a magnet or magnetic coil in proximity with a stationary coil, connected to an electrical circuit.
A voltage can also be produced with a chemical reaction. Batteries and fuel cells convert energy in specially designed cells, where a chemical reaction causes a voltage to exist across two electrodes implanted at two different parts of the cell.
A voltage can be produced by the interaction of light on a photocell. The photons of light interacting with atoms in the photocell, cause an electron to be ejected. The special design of the photocell causes this to occur in such a manner as to produce voltage across the cell.
A voltage can be produced by subjecting a thermocouple to differential temperature. A thermocouple is a relatively simple device composed of two dissimilar metals, joined together at what is referred to as a thermal junction. If one side of the junction is warm, relative to the other side of the junction, a voltage exists across the junction.

What determines the amount of voltage produced by a voltaic cell?
what determines the amount of voltage produced by a voltaic cell?
What are the methods of producing emf?
Presently, there are six known methods for producing a voltage or electromotive force (emf). Some of these methods are more widely used than others, and some are used mostly for specific applications. Following is a list of the six known methods of producing a voltage. 1. FRICTION - Voltage produced by rubbing certain materials together. 2. PRESSURE (piezoelectricity) - Voltage produced by squeezing crystals of certain substances. 3. HEAT (thermoelectricity) - Voltage produced by heating the joint (junction) where two unlike metals are joined. 4. LIGHT (photoelectricity) - Voltage produced by light striking photosensitive (light sensitive) substances. 5. CHEMICAL ACTION - Voltage produced by chemical reaction in a battery cell. 6. MAGNETISM - Voltage produced in a conductor when the conductor moves through a magnetic field, or a magnetic field moves through the conductor in such a manner as to cut the magnetic lines of force of the field.
How the threshold voltage changes the transfer curve for a comparator?
It moves side ways
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
What type of transfomer increases the voltage produced by the source?
step- up transformer

Which of the following factors does not affect the voltage produced in a voltaic cell?
Voltage is not stoichiometric, so increasing the number of moles of a substance will not affect its voltage.
How biomass is produced?
biomass is produced in different ways
