Question

Q4. State Thue of False 1. The potential difference between two ends of each resistance in a parallel combination is the some​

Answer 1

The potential difference between two ends of each resistance in a parallel combination is the some​ is True.

Explanation:  

• If two resistances are connected in parallel, they have the same potential difference across their ends but the current flowing through them will be different.

Answer 2

True. The potential difference between two ends of each resistance in a parallel combination is the same.

• This happens due to Kirchoff's law which states that “summation of voltages of the loop is zero”

So, we can prove this using Kirchoff's rule

$R_{1}I_{1} -(I-I_{1})R_{2} = 0$

Here,

$R_{1}$ = The first resistance.

$I_{1}$ = Current in the first resistance.

$R_{2}$ = The second resistance.

$R_{1}I_{1} = (I-I_{1})R_{2}$

But according to Ohm' Law,

$V_{1} = R_{1}I_{1}$

$V_{2} =(I-I_{1})R_{2}$

$V_{1}=V_{2}=V$

Hence, we can say that the potential difference between two resistances in a parallel combination is the same.
