  2. Overview of Presentation • Definition of Alternating Quantity • RMS or Effective Value • Average Value • Phasor Representation • AC circuit with a pure resistance • AC circuit with a pure Inductance • AC circuit with a pure Capacitance Hope Foundation’s International Institute of Information Technology, I²IT P-14,Rajiv Gandhi Infotech Park MIDC Phase 1, Hinjawadi, Pune – 411057 Tel - +91 20 22933441/2/3 | www.isquareit.edu.in | info@isquareit.edu.in

  3. Definition of Alternating Quantity An alternating quantity changes continuously in magnitude and alternates in direction at regular intervals of time. Important terms associated with an alternating quantity are defined below.

  4. Important Definations Hope Foundation’s International Institute of Information Technology, I²IT P-14,Rajiv Gandhi Infotech Park MIDC Phase 1, Hinjawadi, Pune – 411057 Tel - +91 20 22933441/2/3 | www.isquareit.edu.in | info@isquareit.edu.in 1. Amplitude It is the maximum(+ve or -ve) value attained by an alternating quantity. Also called as maximum or peak value 2. Time Period (T) It is the Time Taken in seconds required to complete one cycle of an alternating quantity. Denoted by T 3. Instantaneous Value It is the value of an alternating quantity at any instant. Instatenios values denoted by small letters 4. Frequency (f) It is the number of cycles that occur in one second. The unit for requency is Hz or cycles/sec. The relationship between frequency and time period can be derived as follows. Time taken to complete f cycles = 1 second Time taken to complete 1 cycle = 1/f second T = 1/f

Angular Frequency (ω) Angular frequency is defined as the number of radians covered in one second(ie the angle covered by the rotating coil). The unit of angular frequency is rad/sec. ω=2πf
