Why power amplifier are called as large signal amplifiers?
in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages
How Calculate the impedance current and voltage values?
To calculate impedance (Z), use the formula ( Z = \frac{V}{I} ), where ( V ) is the voltage across the component and ( I ) is the current flowing through it. If you have the resistance (R) and reactance (X), you can also calculate impedance using ( Z = \sqrt{R^2 + X^2} ). The impedance current can be found by rearranging the formula to ( I = \frac{V}{Z} ). Ensure you use consistent units, typically volts for voltage and amperes for current.
Is input impedance of common emitter fixed quantity?
No, the input impedance of a common emitter amplifier is not a fixed quantity; it varies based on several factors including the transistor's characteristics, biasing conditions, and the values of the input resistors. Typically, it is influenced by the base-emitter resistance and the transistor's current gain (β). Additionally, external components in the circuit can further modify the input impedance. Thus, it is a dynamic value rather than a constant.
What is percentage impedance?
In electrical engineering, the percentage impedance of a transformer is the voltage drop on a full load, which is expressed as a percentage of the specified rated voltage. It's measured by conducting a short circuit test.
What are Factors that determine voltage gain of an amplifier?
The voltage gain of an amplifier is determined by several key factors, including the amplifier's design and configuration (such as common emitter or common source), the values of its components (like resistors and capacitors), and the characteristics of the active devices (transistors or operational amplifiers) used. Feedback mechanisms, both negative and positive, can also significantly influence the gain by stabilizing or enhancing it. Additionally, the load impedance connected to the amplifier affects its voltage gain, as it interacts with the output stage of the circuit.
How do you measure speaker ohms?
Usually speakers are rated by DC impedance, so you can use a simple multimeter to measure their resistance. Typical values are 4 to 32 ohms.

What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
Why are the measured values of resistors different from the nominal values?
All electronic components have a tolerance value in their specification. For resistors, it is specified as a plus or minus tolerance. Typical ranges are 5%, 10%, and 20%, though you can get 1% and 0.1% (matched set) resistors if you want to pay the price. In addition, each measurement has systematic and random error associated with it. All of this must be considered when measuring the impedance of a resistor.

What are the effects of Rs and Rl?
The values of Rs and Rl in a circuit impact the current and voltage levels within the circuit. Rs represents the source resistance affecting the input impedance, while Rl represents the load resistance affecting the output impedance. A variation in these values can cause changes in signal attenuation, power dissipation, and overall circuit performance.
