A circuit breaker is a device that automatically interrupts the flow of electric current in a circuit to protect against short circuits.
Circuit breakers are designed to prevent damage to electrical equipment and wiring caused by excessive current.
They work by detecting abnormal current flow and quickly opening the circuit to stop the flow of electricity.
This helps to prevent overheating, fires, and other hazards that c...
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work by changing the voltage and current levels of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary windings, wrapped around a magnetic core.
When an AC voltage is applied to the primary winding, it creates a magnetic field that in...
A motor is a machine that converts electrical energy into mechanical energy.
Motors are used in various applications such as fans, pumps, and vehicles.
There are two types of motors: AC motors and DC motors.
AC motors are commonly used in household appliances while DC motors are used in electric vehicles.
Motors work by using the interaction between a magnetic field and an electric current to produce motion.
The speed of a ...
AC and DC currents are two types of electrical currents with different characteristics.
AC (Alternating Current) is a type of electrical current that periodically changes direction.
DC (Direct Current) is a type of electrical current that flows in only one direction.
AC is commonly used in household electrical systems, while DC is used in batteries and electronic devices.
AC current is generated by power plants and transmi...
The electric frequency in India is 50hz.
Electricity in India operates at a frequency of 50hz.
This is the same frequency used in most countries in Asia and Europe.
The frequency is important for the proper functioning of electrical appliances.
A relay is an electrically operated switch that uses an electromagnet to mechanically open or close a circuit.
Relays are commonly used in electrical systems to control high voltage or high current circuits with low voltage signals.
They can be used for a variety of applications such as controlling lights, motors, and solenoids.
Relays come in different types such as electromagnetic, solid-state, and reed relays.
They are ...
AC electric current is a type of electrical current that periodically reverses direction.
AC stands for Alternating Current
It is commonly used in household appliances and power grids
The voltage and frequency of AC current can vary depending on the application
Examples of AC current include the power supply in your home and the electricity used to power electric motors
Solar energy is the energy obtained from the sun's radiation and converted into usable energy.
Solar energy is renewable and sustainable.
It is harnessed through the use of solar panels, which convert sunlight into electricity.
Solar energy can be used for a variety of purposes, including powering homes and businesses, heating water, and even powering cars.
It is a clean source of energy, producing no greenhouse gas emissi...
A control system is a system that manages, commands, directs, or regulates the behavior of other devices or systems.
Control systems are used in various fields such as engineering, manufacturing, and automation.
They can be either open-loop or closed-loop systems.
Open-loop systems do not have feedback, while closed-loop systems use feedback to adjust their output.
Examples of control systems include thermostats, cruise co...
Current can be measured using an ammeter.
An ammeter is connected in series with the circuit to measure current.
The ammeter should have a suitable range for the expected current.
The circuit should be turned off before connecting the ammeter.
The ammeter should be connected in the correct orientation.
The reading on the ammeter should be recorded and interpreted correctly.
Voltage can be measured using a voltmeter or a multimeter.
Connect the voltmeter/multimeter to the circuit or component being measured
Set the range of the voltmeter/multimeter to the appropriate voltage level
Read the voltage measurement displayed on the voltmeter/multimeter
Ensure proper grounding and safety precautions are taken
Examples of voltage measurements include measuring the voltage of a battery or power supply

A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two or more coils of insulated wire wound around a core
Primary coil receives electrical energy and induces a magnetic field in the core
Secondary coil receives the magnetic field and converts it back into electrical energy
Used in power distribution, voltage regulation, a...
Transformer principle is based on the phenomenon of electromagnetic induction, where changing magnetic field induces voltage in a coil.
Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, linked by a magnetic core
When alternating current flows through the primary coil, it creates a changing magnetic field
This changing magnetic field induces a voltage in the se...
