Please help with the solution.

Suppose I have two peak phasor voltages, V, = 100245° and V, = 75Z-60°. Circle Your Choices: I. The frequencies associated with the phasors are (0 Hz, 60 Hz, 50 Hz, Unknown). II. The rms value of the first phasor is (100, 70.7, 141, 200) volts. III. If you want to add these two phasors, the frequencies must be (60 Hz, 50 Hz, The same, Integer multiples of a given frequency.)

Please help with the solution.

choose the correct option for ac circuit

A 60 Hz sinusoidal voltage v = 141sinwt is applied to a series RL circuit. The values of the resistance and the inductance are 3 ohms and 0.016 henry respectively. a) Compute the rms value of the current and its phase angle with respect to the voltage.b) write the expression of the instantaneous current.

A series circuit contains only a resistor and an inductor. The voltage V of the generator is fixed. If R = 12 and L = 4.5 mH, find the frequency at which the current is one-half its value at zero frequency. Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise.
