Resistor Box Variable Resistance Box for Measuring Education Classroom

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 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 - Minimum progress value: 1Ω - Rated power: 1WSize Chart:10cmx14cmx5cm/3.94inchx5.51inchx1.97inchPackage Includes:1 Resistance BoxNote:1.This is not infant toy, please take away from children to avoid eating.2.Please allow slightly errors due to manual measurement and different monitors.
