- An electrophorus is a device developed more than 200 years ago for the purpose of charging objects. The insulator on top of a pedestal is rubbed with a cloth, such as wool (Fig. P23.18A). A conductor is placed on top of the insulator, and the conductor is connected to ground by a conducting wire (Fig. P23.18B). (The conductor has an insulating handle, so charge cannot be transferred between the person and the conductor.) The conductor is then removed (Fig. P23.18C). The conductor may then be used to transfer charge to other objects. If the insulators charge after being Ribbed with the wool is negative, what is the charge of the conductor when it is removed?arrow_forwardMost workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting −50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 17 steps?arrow_forwardA magician performs a show with a table tennis ball. Her aim is to the ball in the air without touching it. She prepares her setup as follows; charges the ball with q= -9 x 10ªC, puts it on an insulating stand and uses two conducting parallel plates which are connected to a battery as shown in the figure. The circuit shown in red color is hidden in her glove, sleeve and beneath the insulating stand. The mass of the ball is m = 2.7g and she keeps her hand 15cm above the stand. What must be the minimum potential difference (in volts) that she must apply to the circuit in order to keep the ball in the air? (Take g = 10m/s?) Answer:arrow_forward
- A cell phone battery uses chemistry to create a charge separation between the terminals (anode and cathode). Such a battery is listed as having a capacity of Q = 8.3 × 10^-6 C. (a) If this charge separation consisted entirely of free electrons, how many free electrons would be present in the battery? (b) If the operation of the cellphone requires that 1.1 × 106 electrons move through the circuit every second, how long will a full charge of the battery last in seconds? (c) What current in amperes is passing through the phone?arrow_forwardMost workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting −50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 29 steps and what is the maximum number of steps that any worker should be allowed to take before touching the components if a delicate manufacturing process can be damaged by an electrical discharge greater than 1012 electrons? Make sure to answer both parts of the question.arrow_forwardMany of a computer's internal components, such as the random access memory (RAM) and central processing unit (CPU), are very sensitive to electrostatic discharge (ESD). You have probably experienced ESDs yourself, if you have ever shuffled your feet across a carpeted floor and then touched a metal doorknob. You experienced a small shock, as the excess electrons you stripped from the carpet are transferred to the door knob. If the relative humidity in the room is low, the buildup of charge on the surface of your body, which acts like an insulator, can be significant-more than enough to damage a computer's components. To prevent ESDs, people assembling computers will wear antistatic equipment, such as that shown in the photo. The wrist strap is said to be grounded, which gives the static charge a safe conducting path away from the body, thereby protecting the computer components. In walking across a carpeted hallway, a computer technician acquires a charge of -4.79 x 10-9 C. Assume he…arrow_forward
