Many electronics can be dangerous even after they are shut
off. Consider an a RC circuit of 160.uF and a 1.10M ohms resistor
connected to a 240 -V power source for a long time and then
disconnected and shorted as shown in the figure how long will it be
until the potential difference across the capacitors drops below 70

Many electronics devices can be dangerous even after they are shut off. Consider an RC circuit with a 160-μF-capacitor and a 1.30-MΩ resistor connected to a 210-V power source for a long time and then disconnected and shorted, as shown in the figure. How long will it be until the potential difference across the capacitor drops to below 52.0 V?
Large capacitors can hold a potentially dangerous charge long after a circuit has been turned off,...
Large capacitors can hold a potentially dangerous charge long after a circuit has been turned off, so it is important to make sure they are discharged before you touch them. Suppose a 120 μF capacitor from a camera flash unit retains a voltage of 210 V when an unwary student removes it from the camera. If the student accidentally touches the two terminals with his hands, and if the resistance of his body between his hands is 1.8 kΩ, for...

(2) Q: What can you do to make a parallel-plate capacitor larger? There are several things. Describe as many as you can. In the RC circuit to the right, the capacitor C has a value of 10 uF and the resistor is 144 k 2. The battery has an EMF of 16 V. The circuit is assembled with capacitor is uncharged. At t = 0 s terminal A is connected to terminal B, causing the battery to charge the capacitor....
