Answer:
The current doubles
Explanation:
In a circuit, Ohm's law gives the relationship between voltage, current and resistance:
[tex]V=RI[/tex]
where
V is the voltage
R is the resistance
I is the current
In this problem,
V is held constant
R is halved: [tex]R'=\frac{R}{2}[/tex]
Therefore, the new current is
[tex]I'=\frac{V}{R'}=\frac{V}{R/2}=2\frac{V}{R}=2I[/tex]
So, the current doubles.
