| Posted: 01 Dec 2014 11:43 PM PST The power battery saver circuit when use normal lamp. In some times a lamp that is used have too bright. To adjust the brightness with the variable resistor, it would not be appropriate. because power loss too much. For this circuit can save the power of battery. The brightness of the bulb is equal to […] |
| Super Steady Zener diode circuit Posted: 01 Dec 2014 06:25 PM PST This circuit is used for controls the voltage battery is steady, which the zener diode apply very low current about 1mA only, cause there is ripple voltage about 1 mV at voltage changing between 10 to 30 volts. As circuit the output is fixed to 8V. In circuit the reference voltage is connected to input […] |
| Complementary common-emitter circuit Posted: 01 Dec 2014 04:18 AM PST This complementary common-emitter circuit has special feature that can be applied in 2 model. - Low distortion buffer - The low power output circuit How it works In Figure 1 quiescent current flow through T1 and T2 as voltage (U) and R1, R2 sequence. Look at the circuit will see that difference normal circuit at […] |
