- What is the minimum number of 88@Q resistors that must be connected in parallel to produce an equivalent resistance of 12 0 or less?A 10 kΩ resistor and a 3 nF capacitor are connected across a 10 V battery. The time it takes for the potential across the capacitor to reach 4 V is (a) 17.5 msecs (b) 15.3 msecs (c) 12.0 msecs (d) 18.0 msecs (e) 2.85 msecsA real battery is not just an emf. We can model a real 1.5 V battery as a 1.5 V emf in series with a resistor known as the “internal resistance,” as shown. A typical battery has 1.0 Ω internal resistance due to imperfections that limit current through the battery. When there’s no current through the battery, and thus no voltage drop across the internal resistance, the potential difference between its terminals is 1.5 V, the value of the emf. Suppose the terminals of this battery are connected to a 2.0 Ω resistor.a. What is the potential difference between the terminals of the battery?b. What fraction of the battery’s power is dissipated by the internal resistance?
