Voltage across an unbalanced resistor bridge
In the above circuit R1 = R2 = R4 = 1 ohm and R3 = (11/10) ohm. I have to find the voltage V.
Initially I tried using voltage division in (2 ohm/2.1 ohm) x 10 V = 9.52 V and (2.1 ohm/2 ohm) x 10 V = ...

Why is there a resistor bridge before the amplifier?
I really fail to understand what the resistor bridge before the amplifier does. Can I just connect my inputs to the - and + ports?
This was taken from the datasheet for INA125, and they use this ...

Strange Graetz Bridge Output
Playing with electronics I discovered a strange behaviour of a Graetz bridge. This is my scheme:
The corresponding output looks like this:
I don't understand why I have a additional peak once a ...

Why is there a resistor inline with switch in blender motor?
Our hand-held blender stopped working and I took it apart to see if I could fix it (no, as it turned out).
The circuit was simple; a switch and a 0.47 Ohm (R47) resistor in series with a full bridge ...
