Question
Gautam went for a vacation to the village where his grandmother lived. His grandmother took him to watch 'nautanki' one evening. They noticed a blackbox connected to the mike lying nearby. Gautam's grandmother did not know what that box was. When she asked this question to Gautam, he explained to her that it was an amplifier.
(i) Which values were displayed by the grandmother? How can inculcation of these values in students be promoted?
(ii) What is the function of an amplifier?
(iii) Which basic electronic device is used in the amplifier?
Solution
(i) Following values were displayed by Gautam's grandmother:
(a) Curiosity
(b) Awareness
The inculcation of these values in students can be promoted by positive mental state, improvement in motives and healthy supportive environment.
(ii) The function of an amplifier to increase the amplitude of variation of alternating voltage or current or power.
(iii) Transistor is the basic electronic device used in the amplifier.
