dc characterstics : 1.input offset voltage 2.input bias current 3.input offset current 4. thermal drift ac characterstics:1. CMRR 2. SLEW rate 3. rise time
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.
The capacitor helps to keep the quiesent point fixed. During its operation it bypasses the ac component. If the ac also flows through this emitter link then as we know by parameter equations emitter current and ce voltage changes hence varying q point.
An amplidyne is a form of electromechanical amplifier in which an AC motor drives a DC generator.
power amplifiers are the amplifier which raise the power levels of the signal.the power amplifier may also defined as a device which converts dc power to ac power and whose action is controlled by the ac input signal. Power amplifiers are also known as "LARGE SIGNAL AMPLIFIER".the term large signal arises because they use large part of load line for their operation,but the small signal amplifiers are use only 10% load line for their operation.
Yes, an amplifier can be operated on ac supply.
never heard of a ac amplifier
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
The dc load resistance is Rc but the AC Load resistance is (RcRl). If a load line is drawn the slope of which is -1(Rc Rl) . Then it is called an AC load line and it is to be used when the transistor is operating as an amplifier.

"Characteristics" has four syllables: char-ac-ter-is-tics.
About 1A To 1.5A (or 2A) i tested it one month ago.
