Department of Physics. 8.02 XII. AC Circuits - Worked Examples. Example 1: Series RLC Circuit. Spring 2003. sinusoidal voltage V ( t ) = ( 40.0V ) sin ( 100t ) is applied to a series RLC circuit with L = 160 mH, C = 99.0 μ F , and R = 68.0 Ω . What is the impedance of the circuit?
Derive an equation for the voltage and current through a circuit made of a resis-tor and inductor in series (an RL circuit), and for a circuit made of a capacitor and inductor in series (an LC circuit). Both circuits should give time dependent equations.
Not a surprise, it’s just a wire really. At high frequencies. Open circuit! • Sometimes this can help you with your intuition on the circuit’s behaviour. 14. Go to black Board and. EXPLAIN PHASORS.
Write the formulas for inductive and capacitive reactances. State the effects of a change in frequency on X L and XC. State the effects of a change in inductance on X L and a change in capacitance on XC.
12.1 AC Sources In Chapter 10 we learned that changing magnetic flux can induce an emf according to Faraday’s law of induction. In particular, if a coil rotates in the presence of a magnetic field, the induced emf varies sinusoidally with time and leads to an alternating current (AC), and provides a source of AC power.
The formula for Inductive Reactance multiplies the angular velocity of the AC wave by the value of Inductance: Where 2πƒ or ω is the angular velocity and L is the inductance in. HENRYS. Like resistance, reactance it is measured in ohms, but is separate from the opposition to current caused by any internal resistance within the inductor.
Inductive Reactance, Capacitive Reactance and Impedance. • Resistors: Summary of the table. Resistors have a resistive nature that is characterized as “resistance” and that has the units of ohms. The resistive nature (i.e., the resistance) of a resistor is not frequency dependent.
