    Can anyone help on a question i'm having problems with,

    I need to know how to work out the voltage gain from a wheatstone bridge with an ouput voltage of 94.4 V, the output system is a 1v voltmeter whose scale has been calibrated to read +/- 100N (Don't think this makes any difference to gain)
    Can anyone help where I go from here?

    Any help appreciated.

    I'm not sure if I understand your scenario. It sounds like you're trying to solve a problem that uses a Wheatstone bridge to determine the force in Newtons applied to something (e.g., a bridge, a pressure plate, etc.,).

    Can you post your problem with greater detail?

    Does the volt-meter give the range -1V to 1V, or is it offset at 0.5V?

    Voltage gain is simply Vout/Vin, so 1 / 94.4 is the gain?

    Yeah, agreed with silvrstring, we need more information.
