can you please draw the picture on peper and send me here? as it does not work till now.

output speaker specs is: 4Ohm, 3 Watt

I have cascaded these two , means first i install the Common colletor because of high input impedence and then i apply its output from emitter to LM386 ... but theere is no sound which i applied on common collector base. which type of microphone should i use for this.. please guide me.

<< Obnoxious all caps post fixed by Moderators >>[/color] I have made an audio amplifier using an LM386 IC, but it does not amplify any sound from the microphone. Please help me to improve this using a Darlington pair or any other power transistor like the TIP147/142...

I need help in making my project using Bipolar junction transistor. I'm Engineering student (Ist year). Can someone here suggest me a Funtastic project that i can make easily and impress my teachers as well using BJT transistor. I have rea the Cascade, cascode and Darlington technique to amplify...

Is there any issue to connect the Ammeter in the circuit before or after the load. According to me, the current should remain same in circuit and there should be no restriction for Ammeter connection so it can be placed anywhere in the circuit. please explain why as this question asked to me by...

buddy, i can search it through internet but i know i can't find whatever i needed. so please reply me

What is meant by diode polarity. If we do connect anode to positive and cathode to negative then its means it works on Forward Bias mode. I think positive means higher potential than negative, in other words, if positive terminal which is Anode is to be at 5 volts and negative terminal which is...

Is ohm's law (V=IR) works for both AC and DC. PLz explain in details Also let me know which formula is right for power calculation for AC and DC circuits. (P=VI or P=VICos)
