Unlike voltage transformers, a current transformer has an inverse ratio. This means that a 1000:1 ratio current transformer will create 0.001A in the secondary for every 1A through the wire that is the primary. WebTransformer dynamics is a complex subject. What is important to understand is this: when an AC voltage is applied to the primary coil, it creates a magnetic flux in the core, which induces an AC voltage in the secondary coil in-phase with the source voltage. tiny house trailer frame oregon
