Perform the following steps for the given circuits and define the working region of the BJT’s for the all circuits. a) Find the VCE voltage of the circuit given with (a). b) Calculate the change in VC voltage as a percentage of the circuit given with (a), if the value of β = 60. c) Find the ICmax and ICmin, when the potentiometer has the value of 1MΩ and 0Ω, respectively. d) Find the VC voltage, when the potentiometer has the value of 0.5MΩ. e) When the potentiometer value is increased from 0Ω to 1MΩ, what will be the maximum voltage value of the VC?
Power Amplifier
The power amplifier is an electronic amplifier designed to maximize the signal strength of a given input. The input signal strength is enhanced to a high enough level to drive output devices such as speakers, headphones, RF (Radio frequency) transmitters, etc. Unlike voltage / current amplifiers, the power amplifier is designed to drive core loads directly and is used as a storage block in the amplifier series.
Maximum Efficiency Criterion
In every field of engineering, there is a tremendous use of the machine and all those machines are equipped for their popular work efficiency so it very much important for operation engineers to monitor the efficiency of the machine, planning engineers to check out the efficiency of the machine before installing the machine and design engineers to design machine for higher efficiency than and then the utility will procure their products that will ultimately lead to profit and loss of the company. It indicates the importance of efficiency right from the initial stage as manufacturing units, intermediate stage as planning coordinators, and end-users stage as a utility.
