A: When a 20 om resistor is connected across the terminals of a 12 V battery, the terminal voltage of the battery falls to 10 V. What is the internal resistance of the battery? C: The capacitor is initially uncharged. When the switch is closed to "a", current starts to flow.V=20.0V, C=1.02 muF If the current from the battery is initially 0.2 A, what is the time constant for this RC circuit? (Answer in seconds)
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.
