Electronic Components

- Capacitors (5C10.10) link to picture 5c10_10.htm

-You get a box of capacitors and capicitor parts to show and tell.

-Capacitor parts:

-dielectric wrap

-variable air capacitor

-sample packages

- Inductors

- An inductor has the property V = L(dI/dt), where V is the voltage across the inductor, L is the inductance in henry's and dI/dt is the first time derivative of the inductor current.

- Resistors

-A resistor has the property, V = IR, due to Ohm's law.

- Energy Stored in a Capacitor (5C30.20) link to picture 5c30_20.htm

-Turn on the power supply to charge the 5600 uF capacitor through the power resistor.

-Remove leads from the capacitor WITHOUT TOUCHING THE BINDING POSTS.

-Short the posts with the shaft of a screw driver (not the tip).

-Carefully adjust the voltage from the power supply to light bulb.

-Throw the switch to charge the capacitor. Throw the switch the other way to light the bulb.

-If this is done with 2 capacitors in parallel, the bulb glows twice as long.

-If this is done with 2 capacitors in series, the bulb glows for half as long.
