Detailed Solution

The current through the component will become half.
According to Ohm’s law, at a constant temperature, the current flowing through a component is directly proportional to the potential difference between its terminals, i.e.,

V α I

. if the potential difference increases, the current will increase and vice–versa. Here, the potential difference across the two ends of the component decreases to half. Hence, the current will also decrease to half of its former value.
