I think high resistance.becoz it connects into a parallel combination

Hey mate..
=========
>>As we know, V=I*R, i.e., voltage across a resistor equals the product of its resistance and current flowing through it.
>>Now, if the voltmeter has low resistance, most of the current will pass through it, rather than passing through the resistance. Thus the voltmeter will give an erroneous reading.
>>So as to prevent this sort of a problem, a voltmeter has inherent high resistance.
Hope it helps ®
