An electronic apparatus may have large capacitors at high voltage in the power supply section, presenting a shock hazard even when the apparatus is switched off. A “bleeder resistor" is therefore placed across such a capacitor, as shown schematically in Figure 21.50, to bleed the charge from it after the apparatus is off. Why must the bleeder resistance be much greater than the effective resistance of the rest of the circuit? How does this affect the time constant for discharging the capacitor?
Integrated Concepts 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 RC discharge through a flash tube can limit blurring. Assuming 1.00 mm of motion during one RC constant is acceptable, and given that the flash is driven by a 600F capacitor, what is the resistance in the flash tube?
Show that the power dissipated by the load resistor is maximum when the resistance of the load resistor is equal to the internal resistance of the battery.
The power dissipated in a resistor is given by P = V2/R, which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases. Explain why there is no contradiction here.
The [R drop across a resistor means that there is a change in potential or voltage across the resistor. Is there any change in current as it passes through a resistor? Explain.
Regarding the units involved in the relationship t = RC, verify that the units of resistance times capacitance are time, that is, . F = S.
Refer to Figure 10.17 and the discussion of lights dimming when a heavy appliance comes on. (a) Given the voltage source is 120 V, the wire resistance is 0.800 and the bulb is nominally 75.0 W, what power will the bulb dissipate if a total of 15.0 A passes through the wires when the motor comes on? Assume negligible change in bulb resistance, (b) What power is consumed by the motor?
Show that if two resistors R1and R2are combined and one is much greater than the other (R 1 >>R 2 ): (a) Their series resistance is very nearly equal to the greater resistance R 1. (b) Their parallel resistance is very nearly equal to smaller resistance R2.
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?
Check Your Understanding When using Kirchhoff’s laws, you need to decide which loops to use and the direction of current flow through each loop. In analyzing the circuit in Example 10.7, the direction of current flow was chosen to be clockwise, from point a to point b. How would the results change if the direction of the current was chosen to be counterclockwise, from point b to point a?
When making an ECG measurement, it is important to measure voltage variations over small time intervals. The time is limited by the RC constant of the circuit-it is not possible to measure time variations shorter than RC. How would you manipulate R and C in the circuit to allow the necessary measurements?
A 240-kV power transmission line carrying 5.00x102. A is hung from grounded metal towers by ceramic insulators, each having a 1.00x 109- resistance. Figure 21.51.
