In a universal motor, setting the brushes to the neutral plane can be done by connecting voltage to the armature, a voltmeter to the series field, and adjusting the brush position for a _____ reading on the voltmeter.
A) minimum
B) maximum
Universal Motor
An electric motor that can operate on both AC and DC power sources, often found in portable power tools and appliances.
Neutral Plane
The point at which there is no voltage induced in the armature of a motor or generator.
Voltmeter
An instrument used for measuring the potential difference, in volts, between two points in an electric circuit.

Final Answer :
A
Explanation :
In a universal motor, setting the brushes to the neutral plane minimizes sparking at the brushes. This is achieved by adjusting the brush position until a minimum reading is observed on the voltmeter connected to the series field, indicating minimal current flow through the field due to minimized armature reaction.
