Question.
Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decrease to half its former value. What change will occur in the current through it ?
Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decrease to half its former value. What change will occur in the current through it ?
solution:
We know that $I=V / R$, when potential difference becomes $V / 2$, and resistance remains constant, then, current becomes $1 / 2$ of its former value.
