The scalar operates only on the magnitude of the vector.
So the length of the vector may change ... becoming longer
or shorter ... but its direction doesn't change.

Answer:
The current can be controlled by modifying the resistance value
Explanation:
The current can be controlled by modifying the resistance value, usually a variable resistance device called potentiometer is used. This can be observed mathematically using the ohm law which is defined as voltage equal to the current product by resistance.
V = I*R
where:
I = current [amp]
R = resistance [ohm]
V = voltage [volt]
We can see that if we reduce the resistance the current will be increased
I = v / R
And if we amplify the resistance (R) the current will be diminished
