Question

B) current is larger in higher resistance
C) voltage-drop is same across both
D) voltage-drop is lower in lower resistance
​

Answer 1

Answer:

$\huge \color{purple}\underbrace{Answer}$

C) voltage-drop is same across both

• In parallel connection, all the elements are connected between same two points hence the voltage drop across any number of resistors or other elements connected in parallel is same.

Answer 2

Voltage-drop is same across both resistance.

But why ??

Let us consider the following condition:

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(6.5,0){2}{\line(0,1){3}}\put(0,3){\line(1,0){1}}\put(5.5,3){\line(1,0){1}}\put(0,0){\line(1,0){3}}\put(3.3,0){\line(1,0){3.2}}\put(2.7,-1.8){\bf For (I)}\put(3.2,1.5){\bf R2}\put(3.2,4.4){\bf R1}\put(1.5,3.9){\bf I_1 }\put(1.5,2){\bf I_2 }\put(3,-0.8){\bf\large V}\qbezier(1,3)(1,3)(2.7,4)\qbezier(5.5,3)(5.5,3)(4,4)\qbezier(1,3)(1,3)(2.7,2)\qbezier(5.5,3)(5.5,3)(4,2)\multiput(2.7,4)(0.42,0){3}{\line(1, - 2){0.2}}\multiput(2.9,3.6)(0.42,0){3}{\line(2, 5){0.19}}\multiput(2.9,2.4)(0.42,0){3}{\line(1, - 2){0.2}}\multiput(2.7,2)(0.42,0){3}{\line(2, 5){0.19}}\multiput(0,1.5)(6.3,0){2}{\line(1, - 2){0.2}}\multiput( - 0.2, 1.1)(6.7,0){2}{\line(2, 5){0.19}}\put(3, - 0.3){\line(0, 1){0.6}}\put(3.25, - 0.2){\line(0, 1){0.4}}\multiput(0.4, 1.1)(6.5,0){2}{\sf{I}}\end{picture}$

Now, in case of parallel combination of resistance, the potential drop along each of the resistance is equal irrespective of the value of the resistance.

Hence, potential drop along R1 and R2 will be V, irrespective of the fact that R1 and R2 are different.

That is the reason , we get to see different value of current flowing through the R1 and R2 (because I = V/R).

Option C ) is correct :

Other options are eliminated:

• Current will not be same in both the resistors (Option A)

• Current will be lower in the higher resister (option B)

• Voltage drop will be not be different for the resistances (Option D).
