Leads the current in the capacitor by exactly 90o b. Is in phase with the sinusoidal voltage source c. Is in phase with the voltage across the resistor d. Leads the current in the circuit by 90o e. Lags the current in the circuit by 90oRepresent the following three waveforms on a single phasor diagram.(Use the current as the reference phasor).i = 14 sin 377 t v1=18 sin(377t + π/4) v2 = 16 sin(377t – 60°)3. A sinusoidal voltage is zero and increasing at t= -1.2ms. The next zero crossing occursat t= 5.6ms. Calculate the Period T and Frequency f.

- When you are converting an instantaneous current to a phasor, how does the phase angle being positive or negative affect solving the problem i.e. the representation being (wt - the phase angle in degrees) or (wt + the phase angle in degrees)?What is the sinusoidal expression of the voltage source e, if va= 15sin(5t+50°) and vb=3cos(5t-10°)?A capacitor "C", an inductor "L" and a switch "S" are connected in series. When the switch is open, the plate to the left of the capacitor has charge "Qo". The switch is closed the load and current vary sinusoidally with time. Represent graphically the load "Qo" and the intensity of current "I" as a function of time "t", and explain why the current leads the load by a phase difference of 90°.
