Figure Ql shows a two-legged iron core with air gap on the middle leg. Primary winding and secondary winding are placed around the left and right legs respectively. Nı and N2 are the number of turns of the primary and secondary windings, respectively. The primary current (In) is supplied to the primary winding with the direction indicated in the diagram. Primary Winding Secondary Winding Figure Ql: Two-legged iron core The fringing effect of the air gap plays a role in the flow of the magnetic flux through the secondary winding. Explain how the fringing effect of the air gap can affect the voltage induced across the secondary winding. The explanation should be supported with a relevant equation. |

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.
