Four resistors are connected in parallel across a 9.20−V battery. They carry currents of 150mA, 45.0mA,14.0 mA, and 4.00 mA. If the resistor with the largest resistance is replaced with one having twice the resistance. What is the ratio of the new current in the battery to the original current? What If? If instead the resistor with the smallest resistance is replaced with one having twice the resistance, what is the ratio of the new total current to the original current?
