In a step up transformer the no of turns in the primary and secondary coil are respectively N1 and N2 then
Answers
Answer:
The number of turns (N1) in the primary coil is greater than the number of turns (N2) in the secondary coil.
Explanation:
The other coil is connected to an output circuit with a load resistance and is called “the secondary coil”. Transformers can either step-up or step-down a voltage. In Step-Down Transformer, The number of turns (N1) in the primary coil is greater than the number of turns (N2) in the secondary coil.
Answer:
In a step-up transformer, the number of turns in the primary N1 is less than the number of turns in the secondary N2.
that is N1 < N2
Explanation:
A transformer consists of two coils, one coil is the primary coil the other is the secondary coil wrapped around a metal core.
When an alternating current passes through the primary coil and magnetic field is induced and electromagnetic induction causes a current to flow in the secondary coil.
If the number of loops of wire is the same in both coils then the induced voltage will be same in the secondary coil.
If the number of loops in the secondary coil is greater than the primary coil the voltage will be greater in the secondary coil. This is an example of a step-up transformer.
