By viewing the circuit as a voltage divider the voltage across the capacitor is. A graph of the charge on the capacitor versus time is shown in figure. V c s 1 c s r 1 c s v i n s 1 1 r c s v i n s displaystyle v c s frac frac 1 cs r frac 1 cs v mathrm in s frac 1 1 rcs v mathrm in s and the voltage across the resistor is.
In an rc circuit connected to a dc voltage source voltage on the capacitor is initially zero and rises rapidly at first since the initial current is a maximum.
ϵ c q ϵ c e t r c. An rc circuit is created when a resistor and a capacitor are connected to each other. V t emf 1 et rc v t emf 1 e t rc. Simplifying results in an equation for the charge on the charging capacitor as a function of time.
