Explanation, description, calculation formula, expression

Voltage (V) is measured by volts (V). Current (I) is measured by Amps (A). Power factor (PF) represents some efficiency ratio, e.g 0.8.

Phase (PH) can be single, then a multiplier is equal to one. It can be three-phase, then a multiplier is equal to sqrt(3).

Kilowatts are equal to 1000 watts. The same situation is for kilovolt-amperes, where 1 kVA is equal to 1000 VA.

Formulas for single-phase

Apparent power P_kVA = I * V / 1000

True power P_kW = I * V * PF / 1000

Current I = 1000 * P_kVA/ V

Current I = 1000 * P_kW/ ( V * PF )

Formulas for three-phase (line-to-line)

Apparent power P_kVA = I * V * sqrt(3) / 1000

True power P_kW = I * V * sqrt(3) * PF / 1000

Current I = P_kVA* 1000 / (V * sqrt(3) )

Current I = P_kW* 1000 / ( V * PF * sqrt(3) )

The formulas in the table is for line-to-line voltage. Then the three-phase affects power by sqrt(3) = 1.732.

Formulas for three-phase (line-to-neutral)

Apparent power
P_kVA = 3 * I * V / 1000

True power
P_kW = 3 * I * V * PF / 1000

Current
I = 1000* P_kVA/ ( 3 * V )

Current
I = 1000 * P_kW/ ( 3 * V * PF)

The formulas in the table are for line-to-neutral voltage. Then the three-phase affects power by 3.

So, the connection between electrodynamics and mechanics was clearly understood in 1948. It suggested a significant burst which helped to evaluate and develop the field of physics.

To clarify the definition of the unit of electric current, known as the ampere: The ampere is defined as the constant electric current that, when flowing through two parallel and infinitely long conductors with a negligible circular cross-section in a vacuum, generates a measurable interaction force of 2 × 10⁻⁷ newtons (N) between them at a distance of 1 meter apart.

From this setup, we can derive the value of the magnetic constant, marked as μ₀. It is calculated to be μ₀ = 4π × 10⁻⁷ N/A². We all know it reflects the intrinsic relationship between electric current and magnetic fields in a vacuum. This matter is equivalent to the previously mentioned explanation of the ampere. It creates a solid and developing understanding of electromagnetic interactions.

It is important to state the ε₀ dielectric parameter is a fundamental (very well-known) physical constant. It does not require experimental measurement. This is due to its defined relationship with the origin of electromagnetism, linking it directly to the properties of vacuum. By the way, it enables various calculations in electrical engineering and physics. All in all, as we know, these definitions of physics and electricity allow for a compatible and understandable measurement of electric current.
