A multimeter is a versatile tool used to measure electrical quantities such as voltage, current, and resistance.

• Start by selecting the appropriate measurement function on the multimeter (e.g., voltage, current, resistance).

• Ensure the multimeter is set to the correct range for the expected value.

• Connect the test leads to the appropriate terminals on the multimeter.

• Place the test leads across the component or circuit being measured.

• Read the measurement value on the multimeter d...read more

An induction motor is an AC electric motor in which power is supplied to the rotor by electromagnetic induction.

• An induction motor is commonly used in various applications such as industrial machinery, household appliances, and electric vehicles.

• It operates on the principle of electromagnetic induction, where a rotating magnetic field is created by the stator winding.

• The rotating magnetic field induces currents in the rotor, which in turn creates a torque and causes the motor...read more

EMI EMC test refers to electromagnetic interference and electromagnetic compatibility testing.

• EMI EMC test is conducted to assess the ability of electronic devices to function properly in the presence of electromagnetic interference.

• It involves measuring the electromagnetic emissions from the device under test and ensuring that they comply with regulatory standards.

• EMC testing is performed to ensure that electronic devices do not interfere with each other and can coexist with...read more

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor that is widely used in electronic devices.

• MOSFET is a three-terminal device that can amplify or switch electronic signals.

• It is made up of a metal gate electrode, an insulating layer of oxide, and a semiconductor channel.

• MOSFETs are commonly used in integrated circuits (ICs) and power electronics.

• They are used in various applications such as amplifiers, switches, voltage regulators, and memor...read more

The voltage divider circuit is used to divide a voltage into smaller fractions using resistors.

• The output voltage can be calculated using the formula Vout = Vin * (R2 / (R1 + R2))

• The resistors R1 and R2 are connected in series between the input voltage source and ground

• The voltage across R2 is the output voltage Vout

• The voltage across R1 is Vin - Vout

• The ratio of R2 to the total resistance (R1 + R2) determines the output voltage
