Electrical Resistance Diagram. The resistance spot welding setup consists of a transformer workpieces two copper electrodes and two tongs. The variable resistor can be adjusted in order to give a range of voltages.
Ohmmeter leads connect between points a and b. For low voltage installations ie. Calculate the theoretical resistance of this series combination as given the equation.
Alternatively the resistor can be placed in a circuit and the.
The definition of the resistor is it is a basic two terminal electrical and electronic component used to restrict the current flow in a circuit. Alternatively the resistor can be placed in a circuit and the. Then total voltage across the series connected resistance is given by vs v1 v2 v3. Let v 1 v 2 v 3.
