1)What will happen when 240 VDC supply is connected to
240VAC supply(DC supply +ve is connected to phase of AC
supply & DC supply is to neutral of AC supply).
2)Also what will happen when 240 VDC supply is connected to
240 VAC supply in reverse polarity as of Sr. No 1.

Answer Posted / 12345

when 240vdc supply is connected to 240vac supply then the
power supply becomes zero due to grounding of neutral.

also when the polarity gets reversed only 240vac supply is
been provided to the circuit.
