Unformatted text preview: height of the water tank and its volume provides the constant (voltage) pressure. Another water analogy is of a constant torque motor driving a water pump. The constant torque motor applies the same force to the pump, yielding a constant water pressure. 10V +-V1 I V 5 15 10 independent voltage source The independent voltage source will source whatever current necessary to maintain a constant terminal voltage. reference designator voltage magnitude +-reservoir water tank V pump constant torque motor water pump +-Voltage source analogies...
