Moving Coil Meters
Begins with a current-sensitive element. Though most modern meters have solid state digital readouts, the physics is more readily demonstrated with a moving coil current detector called a galvanometer.

Voltage and Current Meters
Voltage is always measured between two points.Current is measured by passing all the current through the

Electrical Measurements
Charge and Capacitance meter, ammeter, potentiometer, Quadrant electrometer, Electrodynamometer, wattmeter and others.

Electric Meters & Motors
By Andre Ampere and Werner Siemens. Says that when electric currents pass through the movable coil, a magnetic field is produced. This
field interacts with the permanent magnets to cause torque.

AC Current Measurement
Quick, accurate, and safe current measurements can be made on medium and high-voltage systems at
the secondary of instrument current transformers (CT’s) using the TPI A254 Low-Current Clamp-On

AC voltmeters and ammeters
Permanent-magnet meter movements, like permanent-magnet motors, are devices whose motion depends on the polarity of the applied voltage.
