Product Description

Magnetic Junior High School Electrical Demonstration Box

Product Introduction

              Used for middle school physics demonstration experiments, the product mainly consists of a base plate, component sockets, plug wires, switches, battery sockets, small socket sockets, etc. The bottom plate ABS is made of engineering plastic with a size of 400 × 200 × mm. The component sockets are divided into two hole sockets, small four hole sockets, and large four hole sockets, all of which are made of engineering plastic. The surface of each module is marked with the names or circuit symbols of the internal components. The external dimensions of the two hole socket are 74 × 33 × 32mm, the dimensions of the small four hole socket are 73 × 73 × 32mm, and the dimensions of the large four hole socket are 113 × 113 × 32mm. The components of the two hole socket include: one voltmeter (1.5V, 15V dual level), one ammeter (50MA, 500MA dual level), one resistor (100 Ω, 2W), one resistor (200 Ω, 2W), one resistor (470 Ω, 2W), one resistor (1K Ω, 2W), one resistor (4.7 Ω, 2W), one resistor (10K Ω, 2W), and two capacitors (1000uF/16V). Only one lamp socket (screw), two motion units (3V motors), one single pole switch, one buzzer (6V), and one button switch (DS-314). The components of the 4-hole socket include: 1 bridge rectifier (KBP210), 1 inductor coil, 1 potentiometer (100 Ω, 5W), 1 bipolar switch, 1 transformer model (240T, 120T, 60T), 1 relay (6V), 1 voltmeter (0-1.5-15V), and 1 ammeter (0-50-500mA); There is one motor model (vertical small motor model) for the four hole socket. The supporting accessories also include: 1 compass, 20 bridge wires (80mm), 10 bridge wires (150mm), 8 bridge wires (300mm), 2 connecting wires (300mm), 2 connecting wires (450mm), and 15 wiring sockets (outer diameter 6mm, inner diameter 4mm). The product can demonstrate the following experimental items: 1) composition of the circuit; 2) Connect simple series circuits; 3) Connect simple parallel circuits; 4) Measure current with an ammeter; 5) Measure voltage with a voltmeter; 6) Resistance law experiment; 7) Use a sliding resistor to change the current; 8) Series connection of resistors; 9) Parallel connection of resistors; 10) Measure resistance with a voltmeter and ammeter; 11) Measure the electrical power of small light bulbs; 12) Conversion of AC voltage; 13) AC to DC conversion circuit; 14) Research experiments on electromagnets; 15) Experiments on electromagnetic relays; 16) Assemble the DC motor model; 17) DC generator; 18) Fuse experiment.
