+## Why Not to Connect Polarized Capacitors Directly to DC Motors
10
+
11
+- **Polarized capacitors** (like electrolytic types) can only handle **one voltage polarity**.
12
+- If a **DC motor runs in both directions** (CW and CCW), the voltage across its terminals **reverses**.
13
+- This **reverse polarity damages polarized capacitors**, causing:
14
+ - Overheating
15
+ - Leaking
16
+ - Short circuits
17
+ - Power supply shutdowns
18
+
19
+### ✅ Safer Alternatives
20
+- Use **non-polarized capacitors** (e.g., ceramic 0.1–1 µF) directly across the motor terminals.
21
+- Use **polarized capacitors** only on the **power input side** of the motor driver, where polarity is stable.
