- 1What is the equation concerning voltage and current in a capacitor?i = C * dv/dt
- 2When a capacitor is in a steady state how does it behave?It acts as an open circuit as dv/dt = 0 so i = 0.
- 3What does a capacitor oppose?Rapid changes in voltage as this would require a large amount of current.
- 4What does a capacitor do?Stores charge
- 5What is the equation for energy stored by a capacitor?E = 1/2* C * V^2
- 6What is the equation concerning voltage and current in an inductor?v = L * di/dt
- 7When an inductor is in a steady state how does it behave?As a short circuit, as di/dt = 0 so v = 0.
- 8What does an inductor oppose?Rapid changes in current as this would require a large amount of voltage.
- 9What does a inductor do?Stores charge
- 10What is the equation for energy stored by an inductor?E = 1/2 * L * I^2
- 11How do you combine inductors that are in series?The equivalent inductance is the sum of all the inductances in series
- 12How do you combine capacitors that are in series?The inverse of the equivalent capacitance is the sum of the inverse of the capacitances in series
- 13How do you combine inductors that are in parallel?The inverse of the equivalent inductance is the sum of the inverse of the inductances in parallel
- 14How do you combine capacitors that are in parallel?The equivalent capacitance is the sum of all the capacitance in parallel
- 15How to deal with resistor/capacitor and resistor/inductor circuits?
- 16How to solve switching networks questions?Deal with one switch position at a time
Reduce circuit to 1C/1R or 1L/1R
Use general solution formula - 17What is the time constant for an RC circuit?RC
- 18What is the time constant for an LR circuit?L/R
