Four strain gauges of resistance 120 U each are arranged into a DC bridge configuration such that each of the four arms in the bridge has one strain gauge in it. The

maximum permissible current in each strain gauge is 100 mA. What is the maximum

bridge supply voltage allowable, and what power is dissipated in each strain gauge

with that supply voltage?
