Everything you need to know about model railway CDUs
If you''re a model railway enthusiast, you know how important it is to keep your points (or turnouts) working properly. A Capacitor Discharge Unit (CDU) can help ensure that your points operate reliably and minimize the risk of derailments. Here''s what you need to know before buying one. What is a CDU? CDU stands for ''Capacitor Discharge Unit,'' and it is …
How to Discharge a Capacitor? Using Bleeder Resistor, …
There are a couple of techniques to properly discharge a capacitor. We will see the details for each technique one-by-one. No matter how we discharge the capacitor, never touch the leads of the capacitor with your bare hands. Be extremely careful. Using a Metal Object (Screwdriver) This method is not the safest but it can …

Episode 129: Discharge of a capacitor | IOPSpark
When the switch is in position A, the capacitor C gains a charge Q 0 so that the pd across the capacitor V 0 equals the battery emf. When the switch is moved to position B, the discharge process begins. Suppose that at a time t, the charge has fallen to Q, the pd is V and there is a current I flowing as shown. flowing as shown.
How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
