Question

3.
Let the resistance of an electrical component remains constant while
the potential difference across the two ends of the component decreases
to half of its former value. What change will occur in the current through it?​

Answer 1

Answer:

When the potential difference across the two ends of the electrical component becomes half its former value, the current through it also becomes half. Since I = V/R, when potential difference becomes V/2, current becomes I/2 as the resistance (R) of the component remain' constant.

HOPE IT'S HELP YOU

Answer 2

Answer:

current becomes half by putting it in v=ir
