Question

Match the devices given in List I with their uses given in List II: 

• (1) A - h, B - g, C - e, D - f
• (2) A - h, B - f, C - e, D - g
• (3) A - h, B - g, C - f, D - e
• (4) A - e, B - h, C - g, D - f

Hint:

Transistors amplify electrical signals, diodes rectify AC to DC, zener diodes regulate voltage, and capacitors filter signals.

Answer 1

The Correct Option is C

We are given a matching question where we need to match devices with their uses. Let's look at the devices and their corresponding uses: 

1. A (Transistor): - A transistor is used for Amplification of signals. Hence, A - h (Amplifier).

2. B (Diode): - A diode is commonly used as a Rectifier, as it converts alternating current (AC) to direct current (DC). Hence, B - g (Rectifier). 

3. C (Zener diode): - A Zener diode is used for Voltage Regulation, maintaining a stable voltage level. Hence, C - f (Voltage Regulator). 

4. D (Capacitor): - A capacitor is used in Filter Circuits to smooth out voltage fluctuations and to filter signals. Hence, D - e (Filter Circuit). Thus, the correct matching is: - A - h (Transistor as an amplifier) - B - g (Diode as a rectifier) - C - f (Zener diode as a voltage regulator) - D - e (Capacitor as a filter circuit)
