For spark machining of a 5 mm 5 mm square through hole in a solid low carbon steel plate of 5 mm thickness, a brass tool is used with kerosene as the dielectric. The resistance and the capacitance in the r-c circuit of spark generator are 100 ohms and 15 micro-farad, respectively. The supply dc voltage is 220 v and the gap is maintained at such a value that the discharge takes place at 120 v. Estimate the time required to complete the job
