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...
