Q2. What is the active and passive components?
Ans. 
Active components require a power source to operate, while passive components do not.
• Active components require an external power source to function, such as transistors and integrated circuits.

• Passive components do not require an external power source, such as resistors and capacitors.

• Active components can control the flow of electricity, while passive components simply store or dissipate energy.

• Examples of active comp...read more

Q3. What is the difference between resistance and capacitor?
Ans. 
Resistance is the opposition to the flow of current in a circuit, while a capacitor stores and releases electrical energy.
• Resistance limits the flow of current, while a capacitor stores and releases charge.

• Resistance is measured in ohms, while capacitance is measured in farads.

• Examples of resistors include carbon film resistors, while examples of capacitors include ceramic capacitors.

• Resistance dissipates energy in the...read more

Q4. What do you know about SMT ?
Ans. 
SMT stands for Surface Mount Technology, a method of electronic component assembly where components are mounted directly onto the surface of a printed circuit board (PCB).
• SMT components are smaller and lighter than through-hole components, allowing for higher component density on PCBs.

• SMT components are typically mounted using solder paste and reflow soldering techniques.

• SMT technology allows for automated assembly pro...read more
