Transformers Electrical transformers 2.0 / 5 based on 1 rating ? PhysicsElectricityGCSEOCR Created by: BethCreated on: 14-06-12 10:45 A transformer has an input voltage of 240v and an output voltage of 24v is it a... Step-down transformer 1 of 11 How many coils does a transformer have? 2 2 of 11 What type of current has to be used for the transformer to work? AC 3 of 11 where are isolating transformers found? in the bathroom 4 of 11 What is an eddy current? A current in the iron core 5 of 11 How are eddy currents prevented? laminating the iron core 6 of 11 The core of a transformer is made of iron to conduct the magnetic field? True 7 of 11 The output voltage is made higher by... having more turns on the secondary coil than the primary coil 8 of 11 why are isolating transformers used? so there is no direct link to the power supply in areas water is present 9 of 11 occilating flux lines from the primary coil are 'cut' by the secondary coil every time the current changes direction? True 10 of 11 why are coils of wire used? to create a stronger magnetic field 11 of 11
