A resistor and a capacitor are connected in series across an ideal battery having a constant voltage across its terminals as shown.
A resistor and a capacitor are connected in series across an ideal battery having a constant voltage across its terminals as shown. The capacitor initially uncharged. At the moment the switch is closed the voltage across the capacitor is equal to the battery's terminal voltage less than the battery's terminal voltage, but greater than zero. equal to the battery's terminal voltage zero.
When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance
When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...

This circuit consists of an = 6.00 V battery, an R = 49.7 kohm resistor, a C = 149 muF capacitor, a flashbulb, and two switches. Initially, the capacitor is uncharged and the two switches are open. To charge the unit, switch Si is closed: to fire the flash, switch St (which is connected to the camera's shutter) is closed. How long does it take to charge the capacitor to 5.00 V?

In circuit A, a resistor of resistance R is connected across the terminals of a battery with no internal resistance. In circuit B, an identical resistor is connected across a battery which is identical to the battery in the other circuit, except it has internal resistance r. 75.0% less power is dissipated in the resistor in circuit B than the resistor in circuit A. Determine the ratio r/R. Remember to express the answer with three significant digits.
