State whether the following statements are true or false:
(a) The purpose of a transistor amplifier is to enhance the frequency of the input signal.
(b) The gain of an amplifier is the ratio of the output signal amplitude to the input signal amplitude.
(c) The output characteristics of a transistor relate the collector current to the base current.
(d) If the load resistor value is increased the load line gradient is decreased.
(e) In a common-emitter amplifier, the output voltage is shifted by 180? with reference to the input voltage.
(f ) In a common-emitter amplifier, the input and output currents are in phase.
(g) The dynamic current gain of a transistor is always greater than the static current gain
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
A high-performance dragster with a mass of m = 1333 kg can accelerate at a rate of a = 23.5 m/s2. Write an expression for the magnitude of the net force, FNET, that propels the dr
The topic for the project is to study and do calculation in Rotating Biological Contactor although you may choose a different title for your report. The aim is to research how the
How are glass fiber ended? Glass fibers are, usually potted or encapsulated at the single end with the help of an epoxy compound or adhesive. It results on a very hard element
A tank is filled up to a height 2H by a liquid and is placed on a platform of height H from the ground .the distance x from the ground where a small hole is punched to get maximum
A 100V battery is linked across a resistor and causes a current of 5mA to ?ow. Verify the resistance of the resistor. If the voltage is now decreased to 25V, what will be t
LENZ’S LAW A change of flux in a closed circuit induces an emf and sets up a current. The direction of this current is such that its magnetic field tends to oppose the c
The output of an OR gate is linked to both the inputs of a NAND gate. Draw the logic circuit of this combination of getes and write its truth table. Illustrate a plot of potent
