If I take two 24v transformers and wire one side of the output to the other side of the out put. Will the other two wires one on each output give me 48v now.
Thanks

If you wire the secondaries in series, if they are not phased right you will get 0v, otherwise 48.

If they are not phased right will I get short or just 0v.

Ed Williams:

If you connect two 1.5 V batteries in series correctly to add their voltages, meaning the positive of one to the negative of the other, then the voltage from the two in series is about 3 V.

If you reverse one of the batteries, then voltage across the two is approximately 0 V.

If you connect the two batteries in parallel positive to positive, and negative to negative, then the output voltage is 1.5 V with twice the current capability.

If you connect positive to negative, and negative to positive, then you have a dead short and a very high current flow, heat, maybe explosion, and very short battery life.

If you connect two secondaries in series and the phasing is correct then the voltages add. If out of phase the voltages subtract and the voltage is close to 0.

If the voltages add and you short the other two leads together, then big spark, and things burn-up.

The basic rule is that the sum of the voltages around a closed loop is zero. And the sum of the currents at any node is zero. But you may not understand this relative to your question.
