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

Q3. What is Ohm's law?
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more
