Accelerometers

Piezoelectric transducers is an active and inverse transducer-

• False

• True

Seismic type accelerometer measures--------

• Acceleration directly

• infer acceleration from displacement

• calculates velocity

------------------ uses a mass spring damper combination to measure acceleration

• Piezoelectric type accelerometer

• displacement type accelerometer

• thermodynamic type

Wheatstone's bridge is a -----

• AC bridge

• AC and Dc

• DC bridge

Wheatstone bridge is used for the measurement of

• low resistance

• high resistance

• medium resistance

measurement of inductance and capacitance is done by

• AC bridge

• DC bridge

• both AC and DC bridge
