◉ Economical battery tester circuit
① Explain the mechanism of Economical battery tester.
If the voltage source approach the some value of volage, then the voltage on R3 should be small. At this time, it is noticeable how connected battery is consumed by checking the LED.
② Analyze the elements of Economical battery tester and its circuit system.
1) Explain the quality difference in accordance with capacitor.
Capacitor doesn`t affect the system, if it has big capacitance. Since capacitor needs a lot of electrical charge, the battery needs a lot of power. But it is great that observer can observe the LED for a long time.
2) Applying the characteristics of transistor, explain the mechanism of circuit system.
If the value of battery`s voltage is more than minimum voltage, Base node can get value of voltage more than 0.7v. As a result, transistor can work and current flows to LED.
3) Explain the difference in accordance with resistance ratio.
It is used for giving a voltage more than 0.7v to the transistor. Transistor works if base node has voltage more than 0.7v
