(d) The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The . . . . . V re51stance R is slowly 1ncreas1ng as the res1stor heats up. Use Ohm's law: I = E, to nd the rate at which the current I is changing at the moment when R = 400 Q , V = 32 V , dV : 0.2 V/s , and dR : 0.3 Q/s (Note: Resistance is measured in Ohms which is ab: dt abbreviated 9. Voltage is measured in Volts which is abbreviated V . Current is measured in Amperes which is abbreviated A .)
