A physics calculator based on a standard formula. Enter the parameters to compute the result instantly — for coursework, labs, and engineering tasks.

The calculator computes Q (quality) (kvar) from parameters:

Example 1

P, kW = 10, cos φ = 0.85

→ Q (quality): 6.2 kvar

Example 2 (×1.5)

P, kW = 15, cos φ = 1.28

→ Q (quality): — kvar

The “Q (quality)” calculator computes Q (quality) in kvar from 2 parameters: p, kw, cos φ.

A standard physics formula used in educational and engineering tasks.

With parameters P, kW = 10, cos φ = 0.85 the result is 6.2 kvar (Q = P·tan φ).
