## What is VS and VP in transformer?

In a transformer Np / Ns is called the voltage ratio. … This is called a step-down transformer as the voltage is reduced. If Ns is greater than Np then Vs is greater than Vp. The voltage from primary to secondary increases and this is called a step-up transformer.

## What is EMF and voltage?

Emf is the voltage developed between two terminals of a battery or source, in the absence of electric current. Voltage is the potential difference developed between the two electrode potentials of a battery under any conditions.

## What is P in P IV?

P = IV. Electric power (P) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅V= 1 W.

## What is Byjus voltage?

Voltage is the energy that drives charged electrons (current) into a conducting loop from the power supply of an electrical circuit, causing them to perform work such as lighting a lamp. In short, voltage = pressure is calculated in volts, and (V).

## What is full load in transformer?

By full load is meant the load (obviously, on secondary) which would make transformer transfer it’s rated power from primary to secondary. For example when 50 kVA is on full load, it would be transferring 50 kVA from primary to secondary.
