Capacitors

A capacitor stores charge on two plates separated by an insulator. It can smooth power, filter noise, and create timing delays.

Concept illustration. Check the component datasheet before wiring.

Resistance (kΩ)Capacitance (µF)

A capacitor stores charge on two plates separated by an insulator. It can smooth power, filter noise, and create timing delays.

Concept illustration; component appearance and scale are simplified.

Key idea

A capacitor stores charge and resists sudden voltage changes. Larger capacitance stores more charge.

Use in robot

Capacitors can reduce motor noise and smooth logic power when motors start.

Safe wiring

Electrolytic capacitors are polarized. Reversing polarity can damage them. Discharge large capacitors before touching leads.

Classroom check

Compare an LED fade with a small capacitor and a larger capacitor in a safe low-voltage circuit.

Compare current controllers and sensing options before adapting a Nano circuit. Match voltage, interfaces, and timing.
