## 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.
