Canal Ray Tube
To show positive rays. Vertical type, with two fused discs at each end and a perforated cathode in the center through which canal rays pass. The space below the cathode is filled with characteristic glow of cathode rays and the upper portion has canal rays. A magnet brought near the upper portion will repulse the rays, showing the positive nature of the canal rays.

Capacitor Investigation Board
Capacitor Investigation Board is an excellent kit used for study of the charging and discharging of the capacitors. Atoggle switch is used to change the charging and discharging mode of capacitor, external 12 V DC, 2 A supply is used for charging the capacitors through the current limiting resistors. The charging of the capacitor can be viewed on CRO. Once the capacitor is fully charged, it can be discharged by turning the toggle switch towards discharge. The discharging of the capacitor can also be viewed on CRO. These experiments can also be performed using the ammeter and voltmeter. Three different combinations of C&R are provided for observing different wave forms.
