Please answer the following questions and show work. Thank you.
1. true or false. the heavier the current flow for a given voltage, the larger the value for admittance.
2. what is the reactance of a 25 millihenry coil at 600 hertz?
a) 94,000 ohms b) 0.011 ohms c) 785 ohms d)94 ohms
3. In a series R-C circuit, at low frequencies, the total reactance of the capacitor will be high ad the total impedance will be capacitive in nature, at high frequencies the circuit will become _______.
a) balanced b) purely resistance c) more inductive d) purely capacitive
4. In a parallel resonant LC circuit, what is the impedance at the resonant frequency?
a) determined solely by dc resistance b) the maximum impedance value c) zero d) infinity
5. the angle associate with the total impedance is the angle by which the applied voltage leads the source current.
true or false
1. True
2. 94.2 Ohms
3. so the answer is purly capactive.
4. Resonance occurs when capacitive and inductive reactances are
equal to each other. For a tank circuit with no resistance (R),
resonant frequency can be calculated with the following formula:
The total impedance of a parallel LC circuit approaches infinity as
the power supply frequency approaches resonance.
So the answer is d) INFINITY
5. for any configuration , the angle associated with the total impedance is the angle by which the applied VOLTAGE leads the source CURRENT
so it is True
