About This Product
A plug-type resistance box puts a set of known resistances on one panel, so students can change the circuit resistance in steps without rewiring. It is used as the known arm of a bridge circuit and as a variable load when verifying Ohm’s law. Educational Instrument can dispatch the Resistance Box 100 Ohms to laboratories in Uganda, Kuwait, Maldives, Panama and Bosnia and Herzegovina.
Frequently Asked Questions
How is a value set on the Resistance Box 100 Ohms?
Resistance is chosen by plug selection: pulling a tapered brass plug brings that coil into the circuit, up to a total of 100 ohms.
