To answer this question the voltage of the bulbs is needed.
The simple formula you are looking for is W = I x E. Watts = Amps x Volts.
To answer this question a voltage must be given. 25 amps drawn by a bulb seem to be on the high side.
Need to know the voltage of the motor and primary voltage of the transformer.
Depends on the rating of the transformer and the running load of the houses connected to it.
One "bulb" per plant, although they are not technically bulbs.
A 60VA transformer can run only one 50W bulb.
The simple formula you are looking for is W = I x E. Watts = Amps x Volts.
Many inventions were patented one after the other.The included light bulbs and Tesla's energy transformer.
To answer this question a voltage must be given. 25 amps drawn by a bulb seem to be on the high side.
A transformer does many things.
Your question is incomplete -- what about the transformer?
There are many bulbs on a vehicle, need to know which bulbs you want to change.
at first point you should determine the also the secondary voltage of the transformer, secondly you should explain what is the application of this transformer. if you want a special transformer, it is you to decide how much power is needed to be transferred via transformer, and designer tells you it is economical or not. by the way, if i want to refer you to a standard close to your application, following sizes are available for a 20kv/400v transformer: 50kVA,100kVA, 150, 200,315,500,630,800,1200,1600,2000,2500 and 3500kVA i hope this helps you
1 wire is input in this type of transformer.
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
1 Lakh Incandescent bulbs.
