Answer the following statement(s) true (T) or false (F)

1. A 460/115/230 transformer may be connected for two ratios: 460/115 or 230/115. 2. For subtractive polarity, the voltmeter reading (V) is less than the applied voltage. 3. If a 460/115/230-volt, single-phase transformer is to be connected to obtain 460/230 volts, the two secondary coils must be connected in parallel. 4. Taps are arranged in increments of 2.5% or 5% of the primary nominal voltage rating of the transformer. 5. Regulation of constant potential transformers is about 10-25% at the secondary terminals.
