What is CGS unit of voltage?
The statvolt (symbolized statV) is the unit of electromotive force (EMF) or potential difference in the cgs (centimeter/gram/second) electrostatic system. When an EMF of 1 statV exists between two points, then one erg of energy is needed to move one statcoulomb (1 statC) of charge carriers between those two points.

What is the CGS unit of light?
The stilb (sb) is the CGS unit of luminance for objects that are not self-luminous. It is equal to one candela per square centimeter or 104 nits (candelas per square meter). The name was coined by the French physicist André Blondel around 1920.
What is the SI unit of voltage *?
The SI unit for voltage is Volt and is represented by the letter v. volt is a derived SI unit of electromotive force or electric potential.
What is meaning of SI unit of voltage?
SI Unit of Voltage
Volt can be expressed as the potential difference between two points in an electric circuit that imparts one joule (J) of energy per coulomb (C) of charge that passes through the circuit. V = Change in Potential Energy/Charge = ΔU/Q.
What is the other name of voltage?
electromotive force
Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
What is called voltage?
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).
What is the CGS unit of frequency?

How is unit of voltage?
Volt can be stated in SI base units as 1 V = 1 kg m2 s-3 A -1 (one-kilogram meter squared per second cubed per ampere). And finally, volt can be stated in SI base units as 1 V = 1 kg m2 s-3 A -1 (one-kilogram meter squared per second cubed per ampere).
What is current formula?
Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.
What is a voltage symbol?
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827).
What is the SI unit of wavelength?
metre
The SI unit of wavelength is metre usually denoted as m. While measuring wavelength the multiples or fractions of a metre is also used.
What is the CGS unit of mass?

The SI Unit of mass is Kilogram(Kg) and the CGS unit is gram(g).
What is the CGS unit of density?
gram per cubic centimetre
The gram per cubic centimetre is a unit of density in the CGS system, defined as mass in grams divided by volume in cubic centimetres.
What is the symbol of current?
