PHYS 1502Q Chapter Notes - Chapter 10, 23: Energy Density, Electronvolt, Poynting Vector
Document Summary
Add or remove other components to the circuit. Provides energy needed to move charge to establish electric current. Current through the plates is the rate of change of excessive charge on its plates. Charge carriers are electrons that move from lower potential to higher potential (- to +) Direction of the current is as the direction of flow of net positive charge. Assume voltage drop is a positive change in potential. R n = i 1 + i 2 v b = 0. Battery = v b (voltage drop) (voltage drop) (voltage gain when going from - to +) I3 3 + v 2 + i1 1 v 1 = 0. I1 = r r +r r +r r. I3 = r r +r r +r r. I2 2 + i1 1 v 1 = 0. A real battery can be modeled with an internal resistor decreases as i increases.
