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 .
