There are three types of multimeters: analog, digital, and clamp.
Analog multimeters use a needle to display readings.
Digital multimeters display readings on a digital screen.
Clamp multimeters measure current by clamping around a wire.
Examples of multimeter brands include Fluke, Klein Tools, and Extech.
LV cables typically have a voltage rating of 600V or less in construction use.
LV cables are used for low voltage applications in construction.
The voltage rating of LV cables is typically 600V or less.
LV cables are commonly used for power distribution, lighting, and control circuits.
Examples of LV cables include THHN, XHHW, and MC cables.
Yellow lights are used in the field for safety and warning purposes.
Yellow lights are used to indicate caution or warning in the field.
They are often used in construction sites, road work, and other hazardous areas.
Yellow lights can also be used to signal the presence of heavy machinery or equipment.
They are an important safety measure to prevent accidents and injuries.
Yellow lights are easily visible and catch the att
AC voltage is alternating current that changes direction periodically, while DC voltage is direct current that flows in one direction only.
AC voltage changes direction periodically, while DC voltage flows in one direction only
AC voltage is used in household appliances, while DC voltage is used in electronic devices
AC voltage is measured in volts RMS, while DC voltage is measured in volts

Star connection is used in motors to reduce the starting current and increase the torque.
Star connection reduces the voltage applied to each winding, resulting in lower starting current.
It also increases the torque produced by the motor.
Star connection is commonly used in motors with high starting current, such as induction motors.
It is also used in motors that require a high starting torque, such as compressors and pu
There are several types of cables used in construction, including power cables, control cables, communication cables, and more.
Power cables are used to transmit electrical power, such as high voltage cables for transmission lines and low voltage cables for distribution networks.
Control cables are used to transmit signals for controlling machinery and equipment, such as motor control cables and instrumentation cables.

CT stands for Current Transformer and CPT stands for Capacitor Potential Transformer.
CT is used to measure the current flowing in a circuit and step down the current to a level that can be measured by instruments.
CPT is used to measure the voltage of a circuit and step down the voltage to a level that can be measured by instruments.
Both CT and CPT are types of transformers used in electrical systems.
CT and CPT are comm...
I applied via Instahyre and was interviewed before May 2023. There were 2 interview rounds.
The speed difference between stator's rotating magnetic field and rotor's rmf is called slip.
The slip is necessary for inducing current in the rotor and producing torque.
The slip is typically around 1-3% in most induction motors.
Higher slip values can indicate issues with the motor such as overload or mechanical problems.
An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.
They do not require brushes to transfer power to the rotor, making them more reliable and maintenance-free compared to brushed DC motors.
The speed of an induction motor is determined by the frequen...
Synchronisation is the process of coordinating multiple systems or devices to work together in harmony.
Synchronisation ensures that different components or processes are aligned in time.
It is commonly used in electrical systems to ensure that multiple generators are running in phase with each other.
In data communication, synchronisation is important for ensuring that data is transmitted and received at the correct timi...
The speed of a rotor with respect to the stator magnetic field in an induction motor is known as slip speed.
The slip speed is the difference between the synchronous speed of the rotating magnetic field in the stator and the actual speed of the rotor.
It is necessary for the rotor to operate at a speed slightly slower than the synchronous speed in order to induce current and generate torque.
The slip speed allows the roto...
Slip is the difference between synchronous speed and actual rotor speed in an induction motor. Per unit slip is the slip expressed as a fraction of synchronous speed.
Slip is the difference between synchronous speed (speed of the rotating magnetic field) and the actual rotor speed in an induction motor.
Per unit slip is the slip expressed as a fraction of synchronous speed, typically denoted as a percentage.
