A strain gage has a nominal resistance of 100 Ohms and a gage factor of 2.1. If it is used in a quarter bridge with other resistors being 100 Ohms and a supply voltage of 2.3 V, what will be the measured voltage when there is 11900 μstrain acting on the gage?

Vo = 12.5 mV

Explanation:

given data

nominal resistance = 100 Ohms

gage factor = 2.1

other resistors = 100 Ohms

supply voltage = 2.3 V

strain = 11900 μ

solution

we get here voltage so we use here strain output formula

∈α =

put here value

11900 =

solve it we get

Vo =  12495 V

Vo = 12.5 mV

can you make it more obvious. i can't see it properly

answer:

true
