This blog is an attempt to help you familiarize electrical engineering competitive exam questions and answers.
The standard for the exam will be expect of an engineering holder.
This question paper may include the following type of questions
Ans: d
2. The transformer works on the principle of
(a) static induction (b) self induction (c) mutual induction (d) both a and b
Ans: d
3. Transformer is used to change the vales of
(a) Frequency (b) voltage (c) power (d)power factor
Ans:b
Tips: Transformer is used to change the values of voltage and current. Transformer does not change the frequency and wave form.
4. A transformer provides a path for magnetic flux of
(a) high conductivity (b) high reluctance (c) low reluctance (d) low conductivity
Ans:c
5.The emf induced in a coil depends on
(a) the number of its turns
(b) the change of flux linked with it
(c)the time taken to change the flux
(d)all of the above
Ans: d
