XI TEI

Explain the purpose of a soldering iron in electronics.

• Soldering iron is used to increase the resistance of electronic components.

• The purpose of a soldering iron in electronics is to melt solder and create electrical connections between components.

• The purpose of a soldering iron is to cut wires in electronics.

• A soldering iron is used to cool down components in electronics.

What is the first step in circuit design?

• Test the circuit

• Write the code

• Define requirements and specifications

• Choose the components

Why is it important to follow safety protocols when working with industrial electronics?

• To have fun and be adventurous

• Because it's boring to follow rules

• To prevent accidents, injuries, and damage to equipment.

• To test the limits of danger

What is the function of a resistor in a circuit?

• The function of a resistor in a circuit is to store electrical energy

• The function of a resistor in a circuit is to limit the flow of current and control voltage levels.

• The function of a resistor in a circuit is to generate magnetic fields

• The function of a resistor in a circuit is to amplify the current flow

Describe the difference between through-hole soldering and surface mount soldering.

• Through-hole soldering involves components with wire leads inserted into pre-drilled holes on a PCB and soldered on the same side.

• Surface mount soldering involves components with wire leads inserted into pre-drilled holes on a PCB and soldered on the opposite side.

• Through-hole soldering involves components with wire leads inserted into pre-drilled holes on a PCB and soldered on the opposite side, while surface mount soldering involves soldering components directly onto the surface of the PCB without the need for holes.

• Through-hole soldering involves soldering components directly onto the surface of the PCB without the need for holes.

How can you ensure proper ventilation when soldering?

• Use a hairdryer to blow fumes away

• Wear a gas mask for protection

• Solder indoors with all windows closed

• Work in a well-ventilated area, use a fume extractor or fan, and wear a respirator if needed.

Why is it necessary to use ESD (Electrostatic Discharge) protection in industrial electronic work?

• To reduce the efficiency of electronic devices

• To prevent damage to sensitive electronic components from electrostatic discharge.

• To increase the weight of electronic components

• To improve the visual appeal of the workspace

What are the key components of a basic circuit?

• Battery, insulator, resistor, wire

• Voltage source, semiconductor, capacitor, diode

• Power source, conductive material, load, switch

• Generator, non-conductive material, motor, fuse

Explain the concept of current in an electrical circuit.

• Current is the power in an electrical circuit

• Current is the resistance in an electrical circuit

• Current in an electrical circuit is the flow of electric charge carriers through a conductor.

• Current is the voltage in an electrical circuit

What safety equipment should be worn when soldering?

• Sunglasses, sandals, and a raincoat

• Safety goggles, heat-resistant gloves, and a well-ventilated area

• Safety mask, rubber boots, and earplugs

• Apron, knee pads, and a hard hat
