Question

DEFINE SI UNIT OF VOLTMETER​

Answer 1

Answer:

The standard unit of electric field (E-field) strength is the volt per meter (V/m). An E field of 1 V/m is represented by a potential difference of 1 V existing between two points that are 1 m apart. Reduced to base SI units, 1 V/m is the equivalent of one meter kilogram per second cubed per ampere. hope it helps..☺ ...

SI Unit of Voltage

The standard unit of measurement used for the expression of voltage is volt which is represented by the symbol v. However, the volt is a derived SI unit of electric potential or electromotive force. For this reason, volt can further be defined in several ways.

Volt can also be defined as electric potential along a wire when an electric current of one ampere dissipates one watt (W) of power (W = J/s).

V = W/A

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.

It can also be expressed as amperes times ohms, joules per coulomb (energy per unit charge), or watts per ampere (power per unit current)

.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).
