The benefits of fluorescent lighting
When the fluorescent lamp normally emits light, only a lower current is allowed at both ends of the lamp, so the voltage added to the lamp is slightly lower than the power supply voltage, but the fluorescent lamp needs a higher voltage breakdown when it starts to work, so the ballast is added to the circuit, which can not only produce a higher voltage when starting, but also stabilize the current when the fluorescent lamp works.
We aim to gather electrical knowledge and share it with others.
How to Design and Install a Solar PV System?
Design and Installation of Solar PV SystemsModern society relies on energy for daily needs like industry, heating, transport, and agriculture, mostly met by non-renewable sources (coal, oil, gas). However, these cause environmental harm, are unevenly distributed, and face price volatility due to limited reserves—driving demand for renewable energy.Solar energy, abundant and capable of meeting global needs, stands out. Standalone PV systems (Fig 1) offer energy independence from utilities.

Photovoltaic or Solar Cell
DefinitionA photovoltaic (PV) cell is a semiconductor device that converts light into electrical energy. The voltage induced by the PV cell depends on the intensity of the incident light. The term "photovoltaic" originates from its capability to generate voltage ("voltaic") through light ("photo").In semiconductor materials, electrons are bound by covalent bonds. Electromagnetic radiation consists of tiny energy particles called photons. When photons strike the semiconductor material, electrons
