There are many kinds of fire alarms, the more common ones are smoke alarms and heat alarms. Of course, these alarms should also be used according to the place of use and function.For example, in a kitchen with heavy oily smoke, the smoki... -
Potential safety hazards of new energy electric vehicle charging
During the charging process of new energy electric vehicles, due to the large charging current, especially when the charging current is large, the temperature of the charging gun will rise, and the shell of the charging gun will expand d... -
Working theory of NTC thermistor / What is NTC thermistor
NTC (Negative Temperature Coefficient) refers to the thermistor phenomenon and material with a negative temperature coefficient whose resistance decreases exponentially with temperature rise. The material is a semiconductor ceramic made ... -
Difference between NTC and PTC
The thermistor is an electronic component whose resistance value changes with temperature. Within the operating temperature range, its resistance value decreases with increasing temperature/increases with declining temperature. Convers... -
