for a CE transistor amplifier, the audio signal voltage across the collector resistance of 2 kilo-ohms is 2 volt. suppose the current amplification factor is 100. what should be the value of Rb(resistor connected input) in series with Vbb supply of 2 volts if the dc base current has to be 10 times the signal current. also, calculate the dc drop across the collector resistance. what is the difference between dc base current and signal current?
