Description:

- 【Educational】Simple resistance box for students to conduct electrical experiments: verify part of the circuit Ohm law; use to measure unknown resistance; use known resistance to connect to the circuit to adjust the required current; use to measure the electromotive force and internal resistance of the power supply.
- 【Material】Lab Resistor Substitution Box is made of PP material, the resistance value does not change with the temperature, making the resistance measurement result more accurate.
- 【Knob switch】Knob switch designed to make measurement more easier.
- 【Physical】Variable Decade Resistor is Used for physical electricity experiment teaching.
- 【Adjustable 】Teaching Instrument Ohmmeters has Adjustable resistance range 0-9999Ω.

Specification:

- Adjustable resistance range: 0-9999Ω
- Reference power: 0.5W
