20 volts
Actually voltage doesn't CONSUME power. But to answer what I think is your question, it is ENTIRELY dependent on the resistance (R) of the circuit, which in turn denotes the current flow (I). you...
it's depend how many volt power you connect ..such as if you connect 200volt ac line consume 1 amps
You have not supplied enough information. 110 Watts / __Amps = __Volts
Volts does not determine watts. You do not have enough information.
There could be millions.
