e) of current; mA is the unit symbol for milliampere. Other symbols (such as j, exp, Cu) are used to indicate mathematical operations, chemical elements etc. Frequently occurring technical phrases are comm. nly rendered as abbreviations (such as e.m.f., p.d.). In circuit diagrams, grap.
The Greek letter forms used in mathematics are often different from those used in Greek-language text: they are designed to be used in isolation, not connected to other letters, and some use variant forms which are not normally used in current Greek typography.
The ohm (symbol: Ω, the uppercase Greek letter omega) is the unit of electrical resistance in the International System of Units (SI). It is named after German physicist Georg Ohm.

Power factor can be defined as the ratio of real power (Active power) to apparent power. It can also be defined as the absolute value of the cosine of the phase shift between the voltage and current in an AC circuit. It is denoted by the Greek alphabet λ (Lambda). Power factor (λ) = Active power/Apparent power = VI.COS φ/ VI = COS φ
