Question

11.
A transformer has more number of secondary turns than that of
cer
primary. If input voltage is 200V, the output voltage must be
a) 20 V
b) 200 V
C) 250 V
d) 150 V​

Answer 1

Explanation:

An acid will react with a metal to form a salt and hydrogen gas. The general word equation for the reaction between an acid and a metal is as follows:

acid + metal → salt + hydrogen.

The reaction of an acid with a metal:-

diatomic

density

characteristic

presence

chemist

pharmacist

Reaction of hydrogen and oxygen:-

The reaction between a tiny amount of hydrogen and oxygen in the air produces a characteristic 'pop' sound and this serves as test for the presence of hydrogen. You can watch the short video clip in the visit box in the margin to see this 'pop'.

Answer 2

Answer:

The correct answer to this question is:

option (d) - output voltage = 250 V

Explanation:

Transformer:

• A device used to transfer alternating current from one place or circuit to another circuit.
• when converting there will be no change in the frequency of the alternating current
• works on the mutual induction principle

For a transformer,

the number of turns and the voltage are directly proportional to each other, that is:

N ∝ V

N1 / N2 = V1 / V2

Where,

N1 and N2 are the number of turns in the primary side and the secondary side

V1 = voltage in the primary side

V2 = voltage in the secondary side

Given, that the number of turns in the secondary coil is more than the primary coil.

∴ the voltage in the output or secondary coil is greater than the input or primary voltage

Hence, from the given options we can conclude

output voltage  = 250V
