RC Charging and Discharging

Keep one resistor-capacitor loop on screen so capacitor voltage, current, stored energy, and the time constant all stay tied to the same charging or discharging setup.

Why it behaves this way

Explanation

An RC circuit turns capacitor storage into a time-response story. The resistor limits how fast charge can move, the capacitor stores that charge as voltage builds across its plates, and the time constant tau = RC tells you whether the response is fast or slow.

This bench stays intentionally small: one battery, one resistor, one capacitor, and one charge-versus-discharge toggle. That is enough to show why capacitor voltage does not jump instantly, why current is largest right at the start, and how stored energy follows the same changing voltage without turning the page into a general transient-circuit simulator.

Key ideas

01Charging starts with the largest current because the capacitor voltage is initially zero, so almost the full source voltage appears across the resistor.

02As the capacitor voltage rises, the resistor drop and current both shrink, so the charging curve slows down instead of continuing linearly.

03The time constant tau = RC sets the pace. Larger resistance or larger capacitance both make charging and discharging slower.

Bench tools and share links

Keep stable concept links and exact-state sharing tucked away until you actually need to relaunch or share the bench.

Try this setup

Jump to a named bench state or copy the one you are looking at now. Shared links reopen the same controls, graph, overlays, and compare context.

Saved setups

Saved setups are a Premium study tool. Stable concept links still work for everyone.

Checking saved setup access

Open Model Lab is resolving whether this bench can save locally, sync to an account, or open Premium-only compare tools.

Copy current setup

Exact-state sharing is part of Premium. Stable concept and section links still stay available.
