<ul><li>1、The equipment is complete, including a complete set of electromagnetic teaching equipment, which is convenient for teachers to use in teaching. 2、Rugged and durable, with complete equipment, good quality, not easy to damage, and repeatable experiments. 3、With a variety of electromagnetic experiments, it is more intuitive, vivid and specific, which is convenient for students to understand and learn. 4、The measurement is accurate, and the measurement data of the physical electromagnetic experiment box is available for direct use. 5、Applicable experiments, such as series circuit and parallel circuit, current and voltage measurement experiments, etc.
Item Type: Physical Experiment Kit Material: ABS Model: A2 Battery: 1.5V 3xAA Batteries (Not Included) Purpose: Battery teaching experiment in middle and high school Applicable experiment: 1. Static Electricity, Electric Charge 1) Experimental Equipment: 2 x Glass Rods, rubber rods, multi-function brackets, silk, fur 2) Practical Operation: ① Rub the two glass rods with silk, gently place one glass rod on the holder (so that it can rotate freely), and hold the other glass rod close to the glass rod on the holder. Observe the phenomenon. ② Hold the rubber rod rubbed with fur, and approach the glass rod rubbed with silk on the support. Observe the phenomenon. 2. Know simple circuits 1) Experimental Equipment: 2 x Batteries (Not Included), a battery box, a light bulb, a lamp holder, a number of wires, and a switch. 2) Practical Operation: Connect the battery, lamp holder, and switch with wires as shown in the figure to make the small bulb glowing and control its on and off. 3. Use light-emitting diodes to study the direction of current 1) Experimental equipment: 2 x Batteries (Not Included), battery box, several wires, light-emitting diodes, and a switch. 2) The diode has the characteristic of unidirectional conduction. The current flows in from the anode of the light-emitting diode and flows out from the cathode, and the light-emitting diode emits light. If current flows in from the cathode of the light-emitting diode, the light-emitting diode does not emit light. Based on this, the direction of the current can be explored. Note: The light-emitting diodes in this set of experimental equipment can only use 2 x Batteries, otherwise it will be broken down and damaged. 4. Connect series circuit and parallel circuit 1) Experimental Equipment: batteries (Not Included), battery box, bulbs, wires, lamp holders, switches. 2) Practical Operation: ①Compose the circuit, observe and explore the characteristics of the circuit current; ②Change the switching method, explore the role of the series circuit switch, and explore the characteristics of the series circuit: ③Form a parallel circuit, analyze the direction of the current; close each switch separately, look at the function of each switch in the parallel circuit, and analyze which part is a branch circuit and which part is a main circuit. 5. Use an ammeter to measure current 1) Experimental Equipment: 1 x Battery (Not Included), battery box, ammeter, one bulb, one lamp holder, several wires, and one switch. 2) Practical Operation: ①Estimate the current and select the range before measuring. ②The ammeter can be connected to the circuit correctly and connected in series. ③Connect the circuit as shown in the figure to measure the current of a bulb and learn the reading of the ammeter. ④It is absolutely not allowed to connect the ammeter directly to the circuit without any electrical appliances, otherwise the ammeter may be burnt out. 6. Measure the voltage with a voltmeter 1) Experimental Equipment: Battery (Not Included), battery box, voltmeter, bulb, lamp holder, several wires, switch.&lt;</li></ul>
