- Why is it possible for a bird to sit on a high-voltage wire without being electrocuted?arrow_forwardThe immediate cause of many deaths is ventricular fibrillation, which is an uncoordinated quivering of the heart. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart sometimes resumes its proper beating. One type of defibrillator (chapter-opening photo, page 777) applies a strong electric shock to the chest over a time interval of a few milliseconds. This device contains a capacitor of several microfarads, charged to several thousand volts. Electrodes called paddles are held against the chest on both sides of tire heart, and the capacitor is discharged through the patient's chest. Assume an energy of 300 J is to be delivered from a 30.0-F capacitor. To what potential difference must it be charged?arrow_forwardFigure P18.26 shows a voltage divider, a circuit used to obtain a desired voltage Vout from a source voltage . Determine the required value of R2 if = 5.00 V, Vout = 1.50 V and R1 = 1.00 103 (Hint: Use Kirchhoff's loop rule, substituting Vout = IR2, to find the current. Then solve Ohms law for R2.

Why?arrow_forwarddoes the voltage of the battery can decrease if you are using it? how?arrow_forward
- Why do incandescent lightbulbs grow dim late in their lives, particularly just before their filaments break?arrow_forwardThis time-lapse photo of a figure-skater was obtained using a camera with an electronic flash attachment. The energy for each flash of light comes from the electrical energy stored in a capacitor. Explain how the capacitor works in a circuit.arrow_forwardLook at a circuit made up of a resistor, a battery, a capacitor, and a switch. Take the time constant of the circuit to be 3.12 seconds. So if the resistor has a current of 420 mA and a voltage of 12.0 V when the switch is closed, calculate the capacitance of the capacitor.arrow_forward
- If several bulbs are connected in series to a battery, they may feel warm to the touch but not visibly glow. What is your explanation?arrow_forwardYour old car battery with an emf of 7.3 V and internal resistance of 0.5 ohm dies out and won’t let the car’s engine start. The starter motor with resistance of 2 ohm won’t turn over. You borrow a friend’s new car’s live battery with emf of 12.5 V and internal resistance of 0.1 ohm and connected it in parallel to your car’s dead battery to recharge and start the car’s engine. As the dead battery recharges, current from the live battery (ILB) is passed through the dead battery (IDB) and the starter motor, (ISM). Use Kirchhoff’s Laws to find the values of these three (3) currents.arrow_forwardAn incandescent light bulb is partially evacuated. Why do you suppose that is?arrow_forward
