The figure below shows how a bleeder resistor (R = 159.9 kΩ) is used to discharge a capacitor (C = 73.3 µF) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock.
How long will it take to reduce the voltage on the capacitor to 0.100% of its full value once discharge begins?

Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
