C. 11 to 20 volts

D. 50 to 100 volts

Answer: Option B

Solution(By Examveda Team)

Electric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding.
In electric resistance welding, voltage required for heating is 6 to 10 volts.
