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 ?

Explanation

To solve the problem, we will use Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The relationship is given by the formula:

\[ V = I \times R \]

### Step-by-Step Solution:

1. **Identify the initial conditions**:
- Let the initial potential difference (voltage) be \( V \).
