Question

Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decreases to half its former value. What change will occur in the current through it ?

Answer 1

Answer:

current will become half of initial

Explanation:

potential is directly proportional to current

hope the answer will help you

Answer 2

$\huge\bf{Answer}$

The change in the current flowing through the electrical component can be determined by Ohm’s Law.

According to Ohm’s Law, the current is given by

I = V/R

Now, the potential difference is reduced to half keeping the resistance constant,

Let the new voltage be V’ = V/2

Let the new resistance be R’ = R and the new amount of current be I’.

The change in the current can be determined using Ohm’s law as follows:

I'=V'/R' = (V/2)/R =1V/2R=1/2

Therefore, the current flowing the electrical component is reduced by half.
