How do i calculate a capacitor with a specific capacitance loaded with a specific resistance discharge time and reach a specific voltage?

So let's say i have a 22uF capacitor charged with 12 volts and loaded with a 500 ohm load, how many seconds does it take to reach the capacitor's voltage of 6 volts?

    \$\begingroup\$ This is a simple "transient RC" problem. Have you done any investigating yourself about such circuits? \$\endgroup\$ – Elliot Alderson Jun 21 '19 at 11:27

    \$\begingroup\$ I'm sorry but the math on the wikipedia page is as simple as it gets. You might need to improve your math skills before you try to tackle these engineering problems. \$\endgroup\$ – Elliot Alderson Jun 21 '19 at 11:48
