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?

According to Ohm’s law, we have:
I ∝ V or V ∝ I
Since the potential difference (V) decreases to half, i.e.
∴ \(\frac{V}{2}\) ∝ \(\frac{I}{e}\)
Hence, the current flowing through the component will become half.
