An inductor is connected by itself to a 60-Hz ac voltage source. To ensure it has the same inductive reactance when it is connected to a 240-Hz source, would you decrease or increase its inductance value? By what factor should it change? Explain your reasoning.
Answer to relevant QuestionsAn RLC circuit consists of a resistor, a 1.00-μF capacitor, and a 250-mH inductor. If it is driven by an ac voltage source whose frequency is 60 Hz, (a) What is the impedance of an RLC circuit at resonance? (b) How does ...Explain why, under very low frequency ac conditions, a capacitor acts almost as an open circuit while an inductor acts almost as a short circuit. The current in a resistor is given by I = (8.0 A) sin (40πt) when a voltage given by V = (60 V) sin (40πt) is applied to it. (a) What is the resistance value?
