A technician calculates the input power of a parcel conveyor from the measured energy supplied and the measured operating time. The energy reading and the time reading are both 8% greater than their actual values.
How is the result of the power calculation affected by the two errors?
It is too high because the energy reading is too high.
It is too low because the time reading is too high.
It is unchanged because both readings have the same percentage error.
It is too high because both readings are too high.
