Attention (must read before purchasing)
1. User's guide is available in English only!
2. Adult supervision required! This is a physics teaching aid, although there is an instruction manual, student still need to be coached by a teacher or a parent with related knowledge of electricity while using the product.
3. Children's teaching aids only! All parts are not of industrial grade precision.
4. Suitable for children aged 12 and above. Recommended for students in primary school and junior high school
5. Size information on pictures or specifications are for reference only. Manual measurement may have an error of 2-6mm, wires with an error of 2-3cm. And size may vary between products produced in different batches.
6. This product does not include battery. Please prepare 2 pieces of AA batteries yourself.
Ammeter Note
In a parallel circuit, you may find out that the main current is slightly less than the sum of the branch currents. The reason is: the ammeter itself has an internal resistance that reduces the current when it is connected to the circuit. Moreover, the decrease in the main current is more than the decrease in the branch currents, so you may notice that the main current is slightly less than the sum of the branch currents.
Warnings
【ADULT SUPERVISION REQUIRED】
【CHOKING HAZARD】
Please prevent kids from swallowing small parts to avoid choking.
【ELECTRIC SHOCK HAZARD】
Experiments can only use 2 AA batteries. Please prevent children from inserting wires into wall sockets or connecting them to other high-voltage power sources.
【BURN HAZARD】
1. Do not keep the circuit connected for a long time to prevent overheating.
2. Please avoid directly connecting the two ends of the battery, otherwise a short circuit may occur and the circuit may be burned out.
3. Don't connect an ammeter directly to the poles of battery without passing through any electric appliance.
