), featuring problems on voltage drops across components and series/parallel resistor combinations.

The Admiralty's guide provides numerous examples in electrical calculations, which are available in PDF format. These examples cover various aspects of electrical calculations, including:

Maximum allowable drop per core: 1.65 V (two cores in series).

For PF=0.90, new apparent power (S_2 = P / 0.90 = 5.2 / 0.90 \approx 5.78\ \textkVA) New reactive power (Q_2 = \sqrt5.78^2 - 5.2^2 \approx 2.52\ \textkVAR)

Percentage voltage drop = (Vd / V) x 100 = (2.5 V / 400 V) x 100 = 0.625%
