1. When the AC voltage is at 45 degrees of it travel what is the voltage at that
instant.(sine value@45 degrees =.707) The maximum voltage of the circuit is
169VAC. (Formula is maximum voltage (E max) times sine of 45 degrees = point
2. On three phase power each phase is separated from the other phases by __degrees.
3. Convert the binary number 10101 to a decimal number.
