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?

2. (26.60) Many electronics devices can be dangerous even after they are shut off. Consider an RC circuit with a 150.-uF capacitor and a 1.00-MQ resistor connected to a 200.-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 50.0 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...

This lab involves an animation of an RC circuit. By clicking on
the connect battery link below the animation, you close switch 1
and open switch 2 connecting a 40V battery to the resistor and
capacitor in series. By clicking on the disconnect battery link,
you close switch 2 and open switch 1 eliminating the battery from
the circuit and connecting the resistor and capacitor in series. On

5. [RC Circuits] Consider the circuit shown in Figure 5 attached. As shown, the switch is in position "A" for t < 0, and the circuit has been at rest for a long time. At time t = 0, the switch opens and the capacitor starts to drain across the resistor.
