RC Circuits are circuits that have capacitors in them. These circuits have current that varies with time. Key topics covered-
03:06 What are equation for charge in RC Circuits
03:06 What is charge on a capacitor at time t = 0
03:06 What is charge on a capacitor at time t = infinity
04:05 How does a graph of time vs. charge on a capacitor look
04:35 What is equation for current in an RC circuit with time t
04:52 How does a graph of time vs. current in RC circuit look
04:59 What is current in an RC circuit at time t = 0
04:59 What is current in a RC circuit at time t = infinity
05:25 What is equation for voltage of a capacitor at time t
06:00 Definition of capacitive time constant
07:59 What are capacitor discharge equations
Charge accumulation on capacitors in RC circuits varies with time and so does the voltage. Equation derivation of time dependent variables like current and voltage helps us understand the way RC circuits function.
RC circuits can have charging and discharging cycles. In both cycles there are equations that can be used to explain the current, charge and voltage on a capacitor. RC circuits also have a term called capacitive time constant. This has units of time and is equal to product of resistor value into capacitor value
