Question

In an electrical discharge machining process, the breakdown voltage across inter electrode gap (EG) is 200 V and the capacitance of the RC circuit is 50 $\mu$F. The energy (in J) released per spark across the IEG is_______.

• A. 1

Answer 1

The correct option is A 1
$E=\frac{1}{2}C{V}_d^2=\frac{1}{2}\times 50\times {10}^{-6}\times {200}^2$
$=1J$
