Braking Resistor | Resistor Applications | Resistor Guide
What is a Braking Resistor? The property of resistors to dissipate heat can be used to slow down a mechanical system. This process is called dynamic braking and such a resistor is called a dynamic braking resistor (or simply a brake resistor). To decelerate an electric motor, kinetic energy is transformed back into electrical energy.
Capacitors
When capacitors are placed in parallel with one another the total capacitance is simply the sum of all capacitances. This is analogous to the way resistors add when in series. So, for example, if you had three capacitors of values 10µF, 1µF, and 0.1µF in parallel, the total capacitance would be 11.1µF (10+1+0.1).

Where circuit topography allows it is common to add a diode across the inductor to allow the current to ''circulate'' and dissipate energy in the winding resistance. Faster dissipation is often achieved by adding a resistor in series with the diode - initial voltage across the resistor is V=IR and you immediately get decaying I^2R losses.
