Replace an ordinary light bulb with an energy-efficient one and keep the same light intensity – 3 easy steps

Replace an ordinary light bulb with an energy-efficient one and keep the same light intensity – 3 easy steps

As new energy-efficient light bulbs have appeared in stores, so has a new way of calculating the brightness. How should I know to replace an ordinary light bulb with an energy-efficient one but keep the same light intensity? For example, an ordinary 60W light bulb is replaced by an LED or 10-15W CFL light bulb….

What does green tech mean?

What does green tech mean?

Green-tech stands for green technology, that is, a technology that uses clean, renewable energy. Green tech is our future to solve the environmental crisis. Ecological, “clean” or “green” technology aims to preserve the environment through a wide range of technological and technical solutions. The most important green tech features are the production and storage of…

Kirchhoff’s current laws for AC/DC (Look a physicist’s guide)

Kirchhoff’s current laws for AC/DC (Look a physicist’s guide)

There are two of Kirchhoff’s current laws used for DC and AC. They are presented as two equations that describe the ratio of current and voltage in electric circuits. Electric current is a focused movement of charged particles. Movable charged particles are: electrons, in metallic conductors, ions in electrolytes and gases Constant, unchanging (regular) current…

Voltage resonance and Thomson’s formula in alternating current. Examples

Voltage resonance and Thomson’s formula in alternating current. Examples

Voltage resonance and Thomson’s formula are terms related to alternating current. Voltage resonance is only possible in the case of a series connection of a thermogenic resistor, induced thread, and capacitor. Thomson’s formula gives a connection between the circular frequencies of the natural oscillations of a simple oscillator circuit without losses and the parameters of…
