Question
In the circuit given below, $V(t) $ is the sinusoidal voltage source, voltage drop $V_{AB}(t) $ across the resistance $R$  is
✓

Answer

(d)In positive half cycle one diode is in forward biasing and other is in reverse biasing while in negative half cycle their polarity reverses, and direction of current is opposite through $R$  for positive and negative half cycles so out put is not rectified.
Since $R_1$ and $R_2$ are different hence the peaks during positive half and negative half of the input signal will be different.

Given below are two statements :

Statement $I:$ The law of radioactive decay states that the number of nuclei undergoing the decay per unit time is inversely proportional to the total number of nuclei in the sample.

Statement $II:$ The half life of a radionuclide is the sum of the life time of all nuclei, divided by the initial concentration of the nuclei at time $t =0$.

In the light of the above statements, choose the most appropriate answer from the options given below :
