In a common-base amplifier, the phase difference between the input signal voltage and output voltage is

Detailed Solution for TS EAMCET Mock Test - 6 - Question 1

A common-emitter amplifier is shown in the figure (A).
In this Circuit , the output signal is an amplified version of the input signal and is 180 degrees out of phase with the input signal.

     
Common emitter Amplifier
     

     
Common Base Amplifier
     
Figure (B) is a common-base amplifier. In this circuit the output signal is an amplified version of the input signal and is in phase with the input signal. In both of these circuits, the output signal is controlled by the base-to-emitter bias. As this bias changes (because of the input signal) the current through the transistor changes.

In decinormal solution, CH₃COOH acid is ionised to the extent of 1.3%. If log 1.3=0.11. What is the pH of the solution?
Detailed Solution for TS EAMCET Mock Test - 6 - Question 5
The dissociation of acetic acid is:

CH3COOH →  CH3COO- + H+

c – cα  cα
cα

Concentration = 0.1 M

Degree of ionization, α = 1.3 %  

c α = (0.1) * (1.3* 10^-2)  

[H +]=1.3 * 10^-3

pH can be determined as:

-log (H^+) = pH = - log (1.3 * 10^-3) = 2.87

Thus the pH of the solution is 2.87
