EDEXCEL NATIONAL CERTIFICATE/DIPLOMA . unit 67 - further electrical principles . NQF LEVEL 3. OUTCOME 3. TUTORIAL 1 - SINGLE PHASE AC CIRCUITS. unit content 3. Understand the behaviour of single-phase alternating current (AC) circuits Series R, L and C alternating current (AC) circuits: current and phase angle in series combinations of RLC circuits (RL, RC, RLC); construction of phasor diagrams and relationship with voltage and impedance triangles for each of the three types of R, L and C combinations;. power factor (cos ) and power triangle apparent power (S = VI), true or active power (P =. VI cos ) and reactive power (Q = VI sin ); conditions for series resonance inductive reactance equals capacitive reactance (XL = XC); Q factor (voltage magnification) V 1 L.
