Question

what is the si unit of charge sensitivity

Answer 1

i think quantification denoted by Q

Answer 2

pF/ g.   ( pF is pico Farad. )  or  $rad A^{-1}$.

Charge Sensitivity

• The Charge sensitivity is a charge generated in PZT for every 'g' of input acceleration.

• For the accelerometers that are rated in terms of charge sensitivity,  Output voltage (V) proportional to charge (Q) it is divided by the capacitance (C). This type of accelerometer is characterized by the high output impedance. The sensitivity is given in terms of the charge, pico coulombs per unit of acceleration (g).

• Sensitivity describes that the smallest absolute amount of a change that can be detected by a measurement and often expressed in terms of the millivolts, microhms, or tenths of a degree.

• The current sensitivity of the moving coil galvanometer is defined as deflection produced in the galvanometer when the unit current flows through that.

• The SI unit of current sensitivity is $rad A^{-1}$.
