A student in a physics lab mistakenly wired a light bulb, battery, and switch as shown in Figure 21.44. Explain why the bulb is on when the switch is open, and off when the switch is closed. (Do not try this-it is hard on the battery!)
Integrated Concepts Use the ECG in Figure 20.34 to determine the heart rate in beats per minute assuming a constant time between beats. Figure 20.34 A lead II ECG with corresponding arterial blood pressure. The QRS complex is created by the depolarization and contraction of the ventricles and is followed shortly by the maximum or systolic blood pressure. See text for further description.
In the accompanying figure, the rails, connecting end piece, and rod all have a resistance per unit length of . The rod moves to the left at v = 3.0 m/s. If everywhere in the region, what is tire current in the circuit (a) when a = 8.0 cm? (b) when a = 5.0 cm ? Specify also the sense of the current flow.
Some surgery is performed with high-voltage electricity passing from a metal scalpel through the tissue being cut. Considering the nature of electric fields at the surface of conductors, why would you expect most of the current to flow from the sharp edge of the scalpel? Do you think high- or low-frequency AC is used?
A long, inexpensive extension cord is connected from inside the house to a refrigerator outside. The refrigerator doesn't run as it should. What might be the problem?
When charging a capacitor, as discussed in conjunction with Figure 21.38, how long does it take for the voltage on the capacitor to reach emf? Is this a problem?
Integrated Concepts A short circuit to the grounded metal case of an appliance occurs as shown in Figure 23.60. The person touching the case is wet and only has a 3.00 k(resistance to earth/ground. (a) What is the voltage on the case if 5.00 mA flows through the person? (b) What is the current in the short circuit if the resistance of the earth/ground wire is 0.200 ? (c) Will this trigger the 20.0 A circuit breaker supplying the appliance? Figure 23.60 A person can be shocked even when the case of an appliance is grounded. The large short circuit current produces a voltage on the case of the appliance, since the resistance of the earth/ground wire is not zero.
What is the emf x of a cell being measured in a potentiometer if the standard cell’s emf is 12.0 V and the potentiometer balances for Rx= 5,000 and Rs= 2.500 ?
If you wish to take a picture of a bullet traveling at 500 m/s, then a very brief flash of light produced by an EC discharge through a flash tube can limit blurring. Assuming 1.00 mm of motion during one EC constant is acceptable, and given that the flash is driven by a 600F capacitor, what is the resistance in the flash tube?
The dielectric material between the plates of a parallel-plate capacitor always has some nonzero conductivity . Let A represent the area of each plate and d the distance between them. Let represent the dielectric constant of the material. (a) Show that the resistance R and the capacitance C of the capacitor are related by RC=0 (b) Find the resistance between the plates of a 14.0-nF capacitor with a fused quartz dielectric.
