About This Product
A resistance box lets students insert known resistances into a circuit without wiring individual resistors. It is used to verify Ohm’s law and Kirchhoff’s laws and to balance bridge circuits in DC electricity practicals. The Resistance Box, Electronic Type can be supplied on export terms to Saint Lucia, Zambia, Timor-Leste, Latvia, Haiti and Cyprus.
