Answer: 2400V
Explanation:
This is a question on transformer. A transformer is a device used to step up or step down current and voltage. It consists of the primary windings and secondary windings. Each windings possesses both coil and amount of voltage across each coil.
The transformer formula is
Vs/Vp = Ns/Np
Where;
Vs is the voltage across the secondary coil
Vp is the voltage across the primary coil
Ns is the number of turn in the primary coil
Np is the number of turns in the primary coil.
According to the question,
Vs is unknown
Vp is 6000V
Ns is 20turns
Np is 50turns
Substituting the values in the formula given
Vs/6000 = 20/50
Vs = 6000×20/50
Vs = 2400V
Therefore the secondary voltage is 2400V
Answer:
The magnetic effect of electric current is known as Electromagnetic effect. It is observed that when a compass is brought near a current carrying a conductor, the needle of the compass gets deflected because of the flow of electricity.
