An inductive coil of resistance 15 ohms and inductance 0.2H is connected in parallel with a 100 micro farad capacitor to a variable frequency supply. Find the frequency at which the total current taken is in phase with the supply voltage. What is this value of this current if the voltage is 200v. Draw a phase diagram

Complete solution and add phase angles. Please put clear derivation of formulas. Thank you.

b) Two circuits connected in series which voltage drop across at each circuit can be expressed in time TTM domain as V1 (t) =5 sin (3147) V and V2 (1) =15 sin (314t - 30°) V. Sketch the waveforms of these voltages to illustrate peak values and phase relationships. UTM 5 UTM UTM TM S UTM UTM TM 5 UTM 8 UTM
