Why is volt 2nd balance?
So basically, the product of voltage across inductor during ON mode and rise time, and the product of voltage across inductor during OFF mode and the fall time, add up to zero, in other words, “Balance” out. Hence the name, inductor volt-second balance.
What is volt-second?
A volt-second (V·s) is a derived SI unit of magnetic flux, which is equal to weber. By definition, a change in flux of one weber per second will induce in a circuit of one turn an electromotive force of one volt. In SI base units, the dimensions of the weber are (kg·m²)/(s²·A).

Which of the following expression represents a volt?
Which of the following expressions repre- sents a farad? (A) Coulomb/Joule (B) Volt/Coulomb (C) Coulombolt (D) Joule/Volt.
Which of the following has unit volt meter?
Volt Per metre is the standard unit of electric field. An electric field of 1v/m means that the potential difference of 1 volt is 1 metre away form each other. One volt per metre is equal to one meter kilogram per second cubed per ampere.
How do you calculate voltage from Joules and coulombs?
To convert from Joule to Volts you must divide the Joules between the Coulombs which will result in volts. Example : You have an energy of 58 Joule and 33 Coulombs, to how many volts they are equivalent. To know the answer, you must divide 58/33, which will result in: 1.75 Volts.
What is the Volt-second balanced condition for an inductor?
The right way to frame it would be – Inductors need to follow the volt-second balanced condition to reach steady-state operation. If the volt-second condition is not satisfied, the current will continuously increase in the direction of the imbalance, and the inductor may be destroyed.Meaning of volt-second:
Which of the following balance theory is used for inductor?
volt sec balance theory is used for inductor. in that it is considered that the average voltage across inductor in one duty cycle is zero.. similarly amp second balance theory is used for capacitor considering average current in one duty cycle as zero.
What is meant by Volt second balance of a coil?
Since as mentioned the the change of current in coil is zero at steady state, we get that the area of volt-second waveform of coil equals zero, which called volt-second balance. In case of the capacitor, it stores the energy in the form of electric field energy.
What happens if the Volt-second condition is not satisfied?
If the volt-second condition is not satisfied, the current will continuously increase in the direction of the imbalance, and the inductor may be destroyed.Meaning of volt-second: L*di = V*dt. The change in current di is proportional to the product of Volts and time. As long as constant polarity of voltage is applied over
