Question

A Daniel cell-is connected to the primary coil of a transformer. If the output voltage of the Daniel cell is 10 V, and the ratio of secondary to primary coil turns of transformer is 2, then the voltage in the secondary will be O 5 V o 10v O 20 V O Zero​

Answer 1

Answer:

D) zero

Explanation:

as Daniel cell produce Direct current (dc) & direct current does not produce emf .

Answer 2

Answer:

The voltage in the secondary coil, V₂, measured is $20V$.

Therefore, option c) $20V$ is correct.

Explanation:

Given,

The voltage in the primary coil, V₁ = $10V$

The given ratio of the secondary coil turns to the primary coil turns, $\frac{N_{S} }{N_{P} }$ = $2$

The primary coil's number of turns = $N_{S}$

The secondary coil's number of turns = $N_{P}$

The voltage in the secondary coil, V₂ =?

As we know,

• The number of turns is directly proportional to the voltage.

Therefore,

• $\frac{N_{S} }{N_{P} } =\frac{V_{2} }{V_{1} }$

After putting the given values of coil turns and voltage in the equation, we get:

• $2 = \frac{V_{2} }{10}$
• V₂ = $20V$

Hence, the secondary voltage, V₂ = $20V$.
