Sigma Electric Manufacturing Corporation Interview Questions, Process, and Tips

Voltage can be measured using a voltmeter or multimeter.

• Use a voltmeter or multimeter to measure voltage

• Connect the voltmeter or multimeter in parallel to the circuit or component being measured

• Ensure the voltmeter or multimeter is set to the appropriate voltage range

• Read the voltage value displayed on the voltmeter or multimeter

The unit of resistance is ohm (Ω).

• The unit of resistance is a measure of how much a material opposes the flow of electric current.

• It is represented by the symbol Ω (omega).

• Resistance is measured using an instrument called an ohmmeter.

• Examples of resistance values: 10 Ω, 100 Ω, 1000 Ω.

The unit of current is Ampere (A).

• The unit of current is a fundamental unit in the International System of Units (SI).

• Current is the flow of electric charge in a circuit.

• The symbol for current is 'I' and it is measured using an ammeter.

• One ampere is defined as the amount of current that flows through a conductor when a potential difference of one volt is applied across it.

There are various types of paint, including water-based, oil-based, enamel, acrylic, and spray paint.

• Water-based paint is easy to clean up and dries quickly.

• Oil-based paint is durable and provides a glossy finish.

• Enamel paint is commonly used for metal surfaces and provides a hard, glossy finish.

• Acrylic paint is versatile and can be used on a variety of surfaces.

• Spray paint is convenient for small projects and provides

Vernier calliper least count is the smallest measurement that can be read on the instrument.

• It is the difference between the smallest division on the main scale and the smallest division on the vernier scale.

• It is usually 0.1 mm or 0.02 mm for metric vernier callipers and 0.001 inch for imperial vernier callipers.

• The least count determines the precision of the instrument and affects the accuracy of the measurements tak...read more
