During the charging of a capacitor in an RC circuit, how does the voltage across the capacitor change over time?

In an RC circuit with a 12V source, a 100 ,<math-inline>\Omega</math-inline> resistor, and a 10 ,<math-inline>\mu</math-inline>F capacitor, approximately how long will it take for the capacitor to reach 63% of its maximum charge?

As a capacitor discharges in an RC circuit, what happens to the current in the circuit over time?

Three capacitors are connected as follows: $C_1 = 2,\mu\text{F}$ is in series with $C_2 = 4,\mu\text{F}$, and this combination is in parallel with $C_3 = 6,\mu\text{F}$. What is the equivalent capacitance of the entire combination?

In an RC circuit, a resistor with resistance $R = 100 ,\Omega$ is connected in series with a capacitor of capacitance $C = 100 ,\mu\text{F}$. What is the time constant $\tau$ of this circuit?

Capacitors with capacitances of 3 μF and 6 μF are connected in parallel. What is the equivalent capacitance?

In an RC circuit, if the resistance is doubled and the capacitance is halved, what happens to the time constant?

An RC circuit has an initial time constant $\tau$. If a second resistor, identical to the first, is added in series, and a second capacitor, identical to the first, is added in parallel, how does the new time constant $\tau'$ relate to the original?

A capacitor is discharging in a simple RC circuit. What is the final current in the circuit after a very long time?

What components are combined to create RC circuits?
