Question

A potential difference of 0.750 V is needed to provide a large current for arc
welding. If the potential difference across the primary of a step-down transformer
117. what is the ratio of the number of turns of wire on the primary to the number of turns on the secondary?

    The ratio of the number of turns of wire on the primary to the number of turns on the secondary is 1:0.0064.

    Explanation:

    The required voltage ratio is 0.750 by 117  and this is the required turns ratio also  1:0.0064
    .

    It contains a specific number of turns of wire. The turns proportion is characterized as the proportion of turns of wire in the essential twisting to the quantity of turns of wire in the auxiliary winding. Turns proportion can be communicated utilizing Equation. Turns proportion NP NS where NP = number of turns on the essential loop NS = number of turns on the auxiliary curl. The curl of a transformer that is stimulated from an AC source is known as the essential winding (curl), and the loop that conveys this AC to the heap is known as the optional winding (loop)
