a transformer changes 95 v acorss the primary to 875 V acorss the secondary. If the primmary coil has 450 turns how many turns d
natita [175]

Answer:

The number of turns in the secondary coil is 4145 turns

Explanation:

Given;

the induced emf on the primary coil, E_p = 95 V

the induced emf on the secondary coil, E_s = 875 V

the number of turns in the primary coil, N_p = 450 turns

the number of turns in the secondary coil, N_s = ?

The number of turns in the secondary coil is calculated as;

\frac{N_p}{N_s} = \frac{E_p}{E_s}

N_s = \frac{N_pE_s}{E_p} \\\\N_s = \frac{450*875}{95} \\\\N_s = 4145 \ turns

Therefore, the number of turns in the secondary coil is 4145 turns.

Technician A says voltage will not exist between any two points in a circuit if the potential is zero. Technician B says corrosi
nordsb [41]

Answer:

  • <u>Option-(A):</u> If there is no potential or we can say the difference in total amount of charges present inside the system then the voltage's value wont be greater then "0" inside the circuit or system.

Explanation:

  • While, the circuit or system requires the difference in total amount of energy that each atom on that spot has, as this potential energy difference or the total number of charges difference contribute to having a more specified manner of voltage,v in that system. And thus the flow of charges,Q from a point of origination or source towards a region of lower energy is all due to this difference in potential.
