1. What is the emf of a battery that increases the electric potential energy of 0.050 C of charge by 0.60 J as it moves from the negative to the positive terminal? 2 .A thermistor is a device whose resistance varies with temperature. At 20∘C a thermistor's resistance is 10.0 kΩ. When connected to a 1.2 V battery, the current through the thermistor increases by 20 μA as the temperature increases to 30∘C. What is the thermistor's resistance at this...
Physics 2 A standard D cell battery can supply 25 mA at 1.5 V for about 300 hours, and its internal resistance is about 1 Ω. A lift is powered by a battery such that it is 50% efficient and is being used to lift a 60-kg object that is initially on the ground. When the winch is set to a very slow speed, the load resistance is much greater than the internal resistance of the battery. The greatest speed...
