Question
The production of an electromotive force across a conductor when it is exposed to a varying magnetic field is called ____ The induction of an emf in a circuit when the current in that circuit is varied is called _____ _____ is a current due to a variation in the magnetic field surrounding the current's conductor. ____ _____ is a measure of a capacitator's opposition to alternating current The amount of magnetic field passing through a surface is called the ____ The overall resistance to the flow of charge in an RLC circuit is called the ____ Answer the following questions as completely as possible. a. In an RLC circuit, what two characteristics of the circuit are compared using the angle phi? b. In a circuit containing just an AC generator and a capacitor, explain when current I, is ahead of voltage, V. What a major concept from chapter 22, Electromagnetic Induction, links this chapter to chapter 23. Alternating Current Circuits?Explanation / Answer
in the capacitive circuit, the current is leading the voltage so during the zero crossing of the voltage wave the current wave is ahead of the voltage wave V at some angle. here in your question, the only capacitor is connected so the current is leading or ahead of the voltage V at an angle of 90 degrees.
