Can someone help me with this question

d) 3-A 500 ohm resistor is connected in series with a coil with a self-inductance of 800 mH and the maximum It is fed by a sinusoidal source with an amplitude of 15 V and a frequency of 15.92 Hz. According to this Which of the following can represent the voltage across the coil? 14.81cos(wt - 9.09) V 2.5cos(wt - 21.2) V 7.20cos(wt - 11.45) V 2.37cos(wt - 81) V 8.5cos(wt - 41.2) V leave blank 3075

i need the answer quickly

an rc series circuit is connected to a 240v 60 hz power source an ammeter indicates a current of 20 amperes and a wattmeter indicates that the circuit has a true power of 3 kw what is the circuit power factor and what is the capacitance of the capacitor.

نقطتان (2) 10 V * e ÄA 0 15 25 the value of the frequency of the sinusoidal waveform in the figure is equal to 35 t (ms) 60 Hz O 100 cycle O 377 rad/s O 314 rad /s 50 Hz O

If the maximum value of an alternating voltage with a frequency of 35 Hz is 100 V, write the equation for this voltage. A  u= 70,7.Sin2,198t B  u= 63,6.Sin35t C  u= 63,6.Sin35t D  u= 100.Sin219,8t E  u= 63,6.Sin35t

An rms voltage of 22.2 V with a frequencyof 1.00 kHz is applied to a 0.290-mH inductor. (a) What is the rmscurrent in this circuit? (b) By what factor does the current changeif the frequency of the voltage is doubled? (c) Calculate the current for a frequency of 2.00 kHz

An alternating current has the frequency of 62 Hz, then the value of angular velocity is The peak to peak distance of a sinusoidal waveform displayed on a C.R.O. screen is 9 cm and the 'volts/cm' switch is on 21 V/cm. The peak voltage is given by 133.62 V O 94.50 V O 2.33 V 189.00 V
