The unit of resistance is Ohm (Ω).
The unit of resistance is denoted by the symbol Ω (Ohm)
Resistance is measured in Ohms
Named after German physicist Georg Simon Ohm
Commonly used in electrical circuits
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

Voltage is the difference in electric potential between two points in a circuit, measured in volts.
Voltage is the force that pushes electric current through a circuit
It is measured in volts (V)
Voltage is the potential difference between two points in a circuit
Higher voltage means more energy available to move electrons
Voltage can be DC (direct current) or AC (alternating current)

VFD output formula calculates the output voltage and frequency of a variable frequency drive.
The formula is Vout = Vin x (2/√3) x (Fout/Fin)
Vout is the output voltage, Vin is the input voltage, Fout is the output frequency, and Fin is the input frequency
The formula assumes a three-phase system
The output frequency can be adjusted to control the speed of the motor
Example: If Vin is 480V, Fin is 60Hz, and Fout is 30Hz, th
Output VFD drops due to various factors such as overloading, voltage fluctuations, and motor issues.
Overloading of the motor can cause the VFD output to drop.
Voltage fluctuations can also cause the VFD output to drop.
Issues with the motor, such as a faulty winding, can cause the VFD output to drop.
Inadequate cooling or ventilation can cause the VFD output to drop.
Incorrect programming or settings can cause the VFD outp
PLC and HMI can communicate through various protocols such as Ethernet/IP, Modbus, Profibus, etc.
PLC and HMI can be connected through a physical cable or wireless connection
PLC sends data to HMI through the chosen protocol
HMI displays the data received from PLC and sends commands back to PLC
Programming software is used to configure the communication settings
Examples of protocols used for communication are Ethernet/IP,
VFD is used to control the speed of AC motors, while servo is used for precise control of position, speed, and torque.
VFD is used for variable speed control of AC motors
Servo is used for precise control of position, speed, and torque
VFD is typically used in applications where speed control is the primary concern
Servo is typically used in applications where precise control of position, speed, and torque is required

Encoders are devices that convert motion into an electrical signal.
Encoders can be rotary or linear
They work by detecting changes in position or motion
They can be absolute or incremental
Examples include optical encoders and magnetic encoders
