− | A current Sense Resistor is a low value of resistor that is placed in | + | A current Sense Resistor is a low value of resistor that is placed in parallel with some other circuit. We can then measure the voltage across the resistor to compute the current. If the resistor has a low value compared to other components we can ignore the effect on the circuit. We use the word shunt when the voltage is measured by a device that has a fairly low resistance itself. We then have to do a more careful calculation of how the current is shared by the two devices. |
