The coefficient of static friction between the puck and the surface.
In fact, that coefficient describes exactly how "hard" it is to cause the puck to start moving, if it starts from an idle condition.
Answer:
3+2i ohm.
Explanation:
Here we have a complex number operation. According to Ohm's law V=I*R, so:

we need to remove the complex number on the denominator, so we have to multiply by its complement on both side

that gives us:
