Resistor Set
Description
Consisting of six resisters of resistances with different current ratings. The resistors can be used in either the series or parallel mode. The resistors can be connected to any of the desired circuits through the safety sockets provided on the top of the kit for each resistor separately. Accuracy ± 5% . The specifications of each resistor are printed on the top panel of the kit. Mounted in moulded box.
Rheostat
Description
These linear variable rheostats are mounted inside protective cover. The wire is wound on a ceramic tube. Three 4 mm safety socket terminals are provided for connection so the rheostat can serve as variable resistor as well as voltage divider.| Resistance | Max current | |
|---|---|---|
| 0-10Ω | 4 Amp | |
| 0-33Ω | 3.1 Amp | |
| 0-100Ω | 1.8 Amp | |
| 0-330Ω | 1 Amp | |
| 0-1000Ω | 0.57 Amp |
Rheostat, Protected With Single tube
Rheostat, Single Tube
Description
A layer of oxidized resistance wire is wound on a porcelain tube which is supported by end supports. A sliding contact and three 4 mm socket terminals are provided for use as a rheostat or as a potentiometer. Other ranges also available on request.| Ohms | Ampere | Tube length | |
|---|---|---|---|
| 23 | 2.3 | 150mm | |
| 10 | 3.3 | 150mm | |
| 22 | 2.8 | 200mm | |
| 24 | 3.3 | 250mm | |
| 28 | 4.2 | 400mm |
Ruhmkorff Coil
Description
Ruhmkorff Coil produces pulses of high voltage spark from low voltage DC source (6 – 12 V DC). It is suitable for use with gas-filled discharge tubes, vacuum tubes, eudiometers and for general laboratory work. Includes an adjustable vibrator system, primary current polarity reversal, on-off switch, a capacitor enclosed in the box and special alloy contacts. Spark gap at the discharge points can be adjusted by sliding rods back and forth. Spark Length 15 mm.
