25. Two identical resistors are connected in parallel across the terminals of a battery. If you increase the resistance of one of the resistors, what happens to the current through and the voltage across the other resistor? A. The current and the voltage increases. B. The current and the voltage remain the same. C. The current increases and the voltage remains the same. D. The current decreases and the voltage remains the same. 26. Based on the diagram at right, which of the following statements BEST describes it? A. The resistors are connected in parallel because the same current flows through all three resistors. B. The resistors are connected in parallel because different current flows through all three resistors. C. The resistors are connected in series because the same current flows through all three resistors. D. The resistors are connected in series because different current flows through all three resistors. 27. Based on the given diagram below, what is the total power dissipated by the resistors and the power supplied by the battery? R = 20 2 R - 20 1 R= 20 N ww R - 10n R3 - 20 1 v=9v A. Both have 0.9 O. B. Both have 9.0 D. C. For the resistors, it is 0.9 O and 9.0 O for the battery. D. For the battery, it is 0.9 D and 9.0 O for the resistors.
