24. A transformer has a core loss of 160 watts when its primary is connected to a 230- volt 60-cycle source. When the transformer is served by a 40-cycle supply, the impressed voltage is reduced to 4%o of 230 volts, or 153 volts, to maiatain the Bame flux density as on 60 cycles; under this condition the core loss was found to be 96 watts. Calculate the 60-cycle hysteresis and eddy-current loases.

Billy, using a K-map, is designing a VOTE machine which shows "PASS" when 2 or more voters out of 4 voters are in favor. By the way, rule dictates that all 4 voters must cast a vote for their proposed item. What are the minimum required gates (example: how many of what kind: like 5 of 2 input OR gates, ..) to build the vote machine?
