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

Q1. What are the main types of electrical currents?
Ans. 
The main types of electrical currents are AC and DC.
• AC (alternating current) changes direction periodically and is used in household electricity.

• DC (direct current) flows in one direction and is used in batteries and electronic devices.

• Other types of currents include pulsed DC and sinusoidal AC.

• The choice of current type depends on the application and the equipment being used.

Q3. What is the usage of a string of transistors in a series?
Ans. 
A string of transistors in series is used to increase the overall voltage gain of a circuit.
• Transistors in series amplify the input signal sequentially, resulting in a higher overall gain.

• This configuration is commonly used in amplifiers and signal processing circuits.

• For example, a cascade amplifier consists of multiple stages of transistors in series to achieve high gain.

• Each transistor in the series contributes to t
