When to Use Bleeder Resistor?

Bleeder resistors are standard high value resistors which are used to discharge the capacitor in filter circuit. The discharging of the capacitors is really important because even if the power supply is OFF, a charged capacitor can give a shock to anybody.

Why do you need a bleed resistor on start capacitor?

Most replacement start capacitors will not include a resistor. ... The purpose of the resistor is to bleed off residual voltage in the capacitor after it has been disconnected from the circuit after motor start up.

How do I choose a bleeder resistor?

To calculate the appropriate value of the bleeder resistor, consider the relationship among the momentary voltage across capacitor V_t, the bleeder resistor (R), and the initial value V_u. The total capacitance is C and the momentary period is t.
