Capacitor investigation

This apparatus provides a self-contained unit to enable students to study the charge and discharge characteristics of a capacitor. A favourite practical of A level physics made easy.

Let the student's ability shine through and not be hidden by a tangle of wires, connectors and wrongly chosen components.

From opening the box to first results in less than 5 minutes. With everyone in a class using the same apparatus, the potential for group study is very high.

Investigate time constants, resistance and time constants, charge stored and energy stored on a capacitor.

Quick easy collection of data for those stretch and challenge extensions.
 

Use with a (smoothed or regulated) d.c. power supply or with the LAS0009 Battery pack/supply and 3 x 1.5 V cells
 

• Fixed 10,000 uF capacitor and 470 ohm resistor. 
• Colour coded sockets for 4 mm plugs.
• Two blue sockets allow additional resistors to be connected in parallel to the fixed resistor.
• Overlay (under a protective screen) shows the electrical circuit and connection points for a Voltage and Current sensor (or Voltmeter and Ammeter). 
• Connection points for a power supply - up to 12 volts d.c maximum.
• A protection diode (not shown on the unit's circuit diagram) ensures that reverse polarity of a supply cannot damage the capacitor.
