Q2. What is a rectifier?
Ans. 
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
• Rectifiers are commonly used in power supplies to convert AC to DC for electronic devices.

• They can be half-wave, full-wave, or bridge rectifiers.

• Examples of rectifiers include diode rectifiers and silicon-controlled rectifiers (SCRs).

Q3. What is modulation?
Ans. 
Modulation is the process of varying one or more properties of a high-frequency periodic waveform, called the carrier signal, with a modulating signal.
• Modulation is used to encode information on a carrier signal for transmission.

• There are different types of modulation techniques such as Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).

• Example: In AM, the amplitude of the carrier signal is...read more

Q4. What is sampling?
Ans. 
Sampling is the process of selecting a subset of individuals from a larger population to represent the whole.
• Sampling helps in making inferences about the population based on the characteristics of the sample.

• Common sampling methods include random sampling, stratified sampling, and cluster sampling.

• For example, a survey conducted by selecting a random sample of households to represent the entire city's population.

Q5. What is an oscillator?
Ans. 
An oscillator is an electronic circuit that produces a repetitive electronic signal, typically a sine wave or square wave.
• An oscillator generates a periodic waveform without any external input signal.

• It uses positive feedback to sustain oscillations.

• Common types of oscillators include LC oscillators, crystal oscillators, and relaxation oscillators.

• Oscillators are used in various applications such as signal generation,

Q1. What is the difference between resistor and resistance
Ans. 
A resistor is an electronic component that limits the flow of electric current, while resistance is the measure of opposition to current flow.
• Resistor is a physical component made of materials like carbon or metal, while resistance is a property of a material to resist the flow of electricity.

• Resistor is measured in ohms (Ω), while resistance is also measured in ohms.

• Resistors are used in electronic circuits to control...read more
