**RLC Series circuit, phasor diagram with solved problem** An RLC series circuit contains all the three passive electrical components, Resistor Capacitor, and Inductor in series across an AC source. As there is only one path for current in a series combination, the current in all these components is the same in magnitude and phase.

**MEASUREMENTS OF ELECTRICAL QUANTITIES** The basic electrical quantities are electrical current and voltage, electrical charge, resistance, capacitance, inductance and electric power. Electricity is a flow of free electrons carrying negative electric charge from a place of their excess (the place with negative charge) to a place of their deficiency (the place with positive charge). 2.1.

**Per unit system ** A per unit system provides units for power, voltage, current, impedance, and admittance. With the exception of impedance and admittance, any two units are independent and can be selected as base values; power and voltage are typically chosen.
