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)
A 4.0 Ω resistor is connected across the terminals of a 10.0 V battery. If 0.50 A of current flows, what is the internal resistance of the battery? Group of answer choices 8 Ω 16 Ω 20 Ω 4 Ω
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...
hen only a resistor is connected across the terminals of an ac generator (113 V) that has a fixed frequency, there is a current of 0.505 A in the resistor. When only an inductor is connected across the terminals of this same generator, there is a current of 0.408 A in the inductor. When both the resistor and the inductor are connected in series between the terminals of this generator, calculate the following. (a) the impedance of the series combination...

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.
