A dc generator is rated at 20 kW, 250 V, and 80 A when it rotates at 1500 rpm. The resistance of the armature windings is 0.34 2. Part A Calculate the "no-load" voltage at 1500 rpm (when there is no circuit hooked up to the generator). Express your answer using two significant figures. V ΑΣΦ Val = 0 ? kV Review | Constants Calculate the full-load voltage (i.e. at 80 A) when the generator is run at 700 rpm. Assume that the magnitude of the magnetic field remains constant. Express your answer using two significant figures. V2 = ΜΕ ΑΣΦ | ? V
