How alternating current is indicated: determining what is the difference between AC and constant value Construction And Repair

An easy way to visualize the difference between AC and DC currents is to plot their direction versus time. The first will look like a straight line, and the second will look like a wavy line. One c...

Three-phase current power: some formulas for calculating and methods of measuring power Construction And Repair

Alternating and direct currents differ from one another in many parameters, and especially in the presence of phases in the first type. These differences are associated with more complex formulas a...

Rated current: general definition, selection of circuit breaker and wiring Construction And Repair

If you need to choose a circuit breaker for the electrical panel, you must first study its characteristics. It is important to know what the load will be on it. The most basic characteristic that t...

Direct and alternating current on the diagrams: their designations, areas of application of DC current Construction And Repair

Electrical energy accompanies us at every step. Without it, the life of any person is unthinkable. Throughout our lives, we in one way or another are faced with the manifestations of electricity. T...

How direct current differs from alternating current: definition and difference between them Construction And Repair

Electric current is called the transfer of charge or the movement of charged particles between points with different electric potentials. Ions, protons and / or electrons can carry an electric char...

Current limiters to protect electrical and electronic networks from the destructive effects of voltage Construction And Repair

Current limiter (OT) - a device that is used in electrical or electronic circuits to reduce the upper limit of direct (DC) or alternating (AC) current supplied to a load. This ensures timely reliab...

Ohm's law for an alternating current circuit: the formula for the relationship between electrical quantities, the calculation procedure Construction And Repair

The fundamental position describing the dependence of current, resistance and voltage from each other is Ohm's law for an alternating current circuit. Its main difference from the position of the s...

Current power: a unit of measurement of an electrical quantity, formulas for its determination Construction And Repair

Power is a physical indicator. It identifies the work done over time to help measure energy change. Thanks to the unit of measurement of current power, it is easy to determine the high-speed energy...

The strength of the electric current: how and in what it is measured, according to what formulas it is, how it is indicated Construction And Repair

The definition of the concept of current strength sounds like this: these are charged particles (electrical charges) that move in a certain direction and are called electrons.Let's imagine that a c...

Parallel resonance in an alternating current circuit: physical meaning and application, formulas and calculation methods Construction And Repair

The physical phenomenon of parallel resonance is widely used in radio electronics. To build oscillatory circuits consisting of active and reactive resistances, a circuit should be assembled from re...
