Final answer:
The load power for a buck-boost transformer that boosts the source by 30 volts at a current of 40 amperes is 1200 watts (or 1.2 kilowatts).
Explanation:
The load power of a buck-boost transformer, we need to know the voltage and current of the source and the voltage boost provided by the transformer. In this case, the source is boosted by 30 volts and the current is 40 amperes. The load power can be calculated using the formula P = IV, where P is the power, I is the current, and V is the voltage. So, the load power is 30 volts multiplied by 40 amperes, which equals 1200 watts (or 1.2 kilowatts).
