WebIn this case the bleeder current is much larger than 10% but the circuit has the practical benefit that even if the load is removed (ie open circuit) the voltage does not change more than 10%. This also gives the benefit of meaning that the voltage divider and load can be analysed separately as they do not interfere with each other. http://www.learningaboutelectronics.com/Articles/Capacitor-discharge-calculator.php
