Question : 12 of 65

Marks: +1, -0

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

Your Answer:

Validate

Solution:

E= \;\; \;{1}/{2} × \;\text " Capacitance "\; × \;\text " voltage "\;^{2}

E=0.5 × 50 × 10^{-6} × 200^{2}=1 J
