Question

15 Assertion: The current flowing through each resistor is the same when connected in series Reason: parallel The voltage drop across each resistor remains the same when connected in​

Answer 1

Answer: Assertion) Current flows in a circuit. In other words, it's the rate of flow of electric charges. Other than i=

dt

dq

​

, Current is also given by I=nAEv

d

​

 which says something that it depends upon the drift velocity of electrons. The drift velocity is the average velocity between two successive collisions. This velocity prevents the electrons from accelerating continuously. Ok. Let's consider a circuit with three resistors with resistances in an increasing order R

;R

.

First, current enters R

1

​

. After some collisions (causes heat generation), it exits the resistor. Now, the same current enters and exits R

​

 and R

​

 in the same manner. The rate of flow of charges is always the same (the current entered and exited the resistors with same magnitude). Only the drift velocities vary in different resistors.

If the same are connected in parallel (Now, we look into the resistors), current flows through R

​

 easily. Because, R

3

​

 requires a lesser v

d

​

 (i.e) Electrons entering R

3

​

 would exit within a small period of time relative to the other two (thereby increasing the rate). As a result, larger current would be observed.
