Well.I am new to electronics. I have just started creating small circuits. Coming to the point,I have a circuit with 5v input and current in the circuit is 2ma but I have a requirement to increase it to 200 ma in a circuit. When I googled for the solution, I found threads like increase voltage or decrease resistance (using V=IR) to increase the current But those values are to be fixed in my circuit. Basically I Studied that CC transistor has high current gain so I thought to use it in my circuit but people on internet says it amplifies signals current(probably an ac signal i guess so) and I am unable to understand what does that mean.
What does voltage gain and current gain mean in a Transistor? Does it amplify only ac signals? If I apply 5v dc input to a CB configuration that has high voltage gain, Wont it make it as 20v at the output? Similarly if I input 10 ma current of a DC circuit to CC amplifier, Does not the CC make it as 1 Amp at the output?
After seeing the comments I added the circuit picture. Now I want to increase the current in the circuit where R is 2.5Kohms and E1 is 5volts and the current is 2 ma but I want the current to be increased to 200 ma but keeping the R1 and E1 fixed. But Im unable to figure it how.Please kindly clear me this. and let me know what should i prefer if i want to increase current in a circuit keeping the voltage and resistance values constant in a circuit.Thanks
