1. Explain what is the instantaneous values of AC AND phase shift angle are. Explain what the effective and average values of AC are. How are they related with amplitude.
2. Draw a calculated conductivities triangle for the circuit with a parallel connection of RLC- elements and write down the corresponding relations for them .
3. Write down the complex effective values for given instantaneous values of voltage V=25sin(314t +pie/2)v and current I=0.5(314t+pie/3). Define the admittance of the circuit in complex fork (exponential and Algeriac notation ), active and reactive conductivities . Draw the voltage and current vector diagram .
