plz help! A dc generator is rated at 19 kWkW , 250 VV, and 76 AA when it rotates at 1200 rpmrpm . The resistance of the armature windings is 0.34 ΩΩ . Q1:Calculate the "no-load" voltage at 1200 rpmrpm (when there is no circuit hooked up to the generator). Q2:Calculate the full-load voltage (i.e. at 76 AA ) when the generator is run at 780 rpmrpm . Assume that the magnitude of the magnetic field remains constant.
