SOLENOID
What is a Solenoid?
Solenoid is the common name for a wire coil used as an electromagnet. It also refers to any device that converts electrical energy into mechanical energy using a solenoid. The device generates an electrical current magnetic field and uses the magnetic field to generate linear motion. Common applications

Solar Panel
Introduction to Solar Panel
The term solar panel is used colloquially for a photovoltaic board. The PV module is an assembly of photovoltaic cells mounted in the installation framework. Photovoltaic cells use sunlight as a source of energy to produce direct electricity. A set of PV modules is called a PV panel and a panel system is ca

Transformer Losses
What are transformer losses?
Transformer losses are caused by an electrical current flowing in the coils and by the alternating magnetic field in the core. Losses associated with the coils are called load losses, while losses caused in the core are called no-load loss. In any electrical system, 'loss' can be described as the di

RELAY
What is a relay?
Relays are switches designed to close and open circuits electronically as well as electromechanically. It controls the opening and closing of the electronic circuit contacts. When the relay contact (NO) is opened, the relay is not energized by the open contact. However, if the relay is closed (NC), it is not energized due t

What is a Voltmeter?
Voltmeter is an electrical measurement device used to measure a potential difference between two scales. A voltmeter is a device used to measure the electrical potential difference between two points in an electrical circuit. Analog voltmeters shift the pointer over a scale in accordance to the voltage of the circuit; digital
