Capacitance of Circuit Solution

STEP 0: Pre-Calculation Summary

Formula Used

Capacitance = ((0.03/Frequency of Cutting)^2)/Inductance
C = ((0.03/f_cut)^2)/L
This formula uses 3 Variables

Variables Used

Capacitance - (Measured in Farad) - Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.
Frequency of Cutting - (Measured in Hertz) - Frequency of Cutting refers to how often a machine or tool is engaged to trim, shape, or remove material from a workpiece during the production process.
Inductance - (Measured in Henry) - Inductance is the tendency of an electric conductor to oppose a change in the electric current flowing through it.

STEP 1: Convert Input(s) to Base Unit

Frequency of Cutting: 0.005 Cycle per Second --> 0.005 Hertz (Check conversion here)
Inductance: 5.7 Henry --> 5.7 Henry No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C = ((0.03/f_cut)^2)/L --> ((0.03/0.005)^2)/5.7

Evaluating ... ...

Frequency of Cutting from Capacitance and Inductance

Go Frequency of Cutting = 0.03/sqrt(Inductance*Capacitance)

Inductance of Circuit from Cutting Frequency

Go Inductance = ((0.03/Frequency of Cutting)^2)/Capacitance

Capacitance of Circuit

Go Capacitance = ((0.03/Frequency of Cutting)^2)/Inductance

Frequency of Cutting using Charging and Sparking Time

Go Frequency of Cutting = 1/(Sparking Time+Charging Time)

Sparking Time from Frequency of Cutting

Go Sparking Time = 1/Frequency of Cutting-Charging Time

Charging Time from Cutting Frequency

Go Charging Time = 1/Frequency of Cutting-Sparking Time

Capacitance of Circuit Formula

Capacitance = ((0.03/Frequency of Cutting)^2)/Inductance
C = ((0.03/f_cut)^2)/L

How the spark is produced in Electric Discharge Machining ?

A typical circuit used for supplying the power to an EDM machine is named as the relaxation circuit. The circuit consists of a DC power source, which charges the capacitor ‘C’ across a resistance ‘Rc’. Initially when the capacitor is in the uncharged condition, when the power supply is on with a voltage of Vo, a heavy current, ic, will flow in the circuit as shown to charge the capacitor.The relaxation circuit as explained above was used in the early EDM machines. They are limited to the low material removal rates for fine finish, which limits its application. This can be explained from the fact that the time spent on charging the capacitor is quite large during which time, no machining can actually take place. Thus the material removal rates are low.

How to Calculate Capacitance of Circuit?

Capacitance of Circuit calculator uses Capacitance = ((0.03/Frequency of Cutting)^2)/Inductance to calculate the Capacitance, The Capacitance of circuit formula is defined as the equivalent capacitance of all the capacitors connected in the relaxation circuit of EDM to produce spark.
