SD Infra and MEP Services Electrical Estimation Engineer Interview Questions and Answers

Secondary current of a transformer is determined by the turns ratio and primary current.

• Secondary current is directly proportional to the primary current.

• It is inversely proportional to the turns ratio of the transformer.

• Formula: I2 = (N1/N2) * I1, where I2 is secondary current, N1/N2 is turns ratio, and I1 is primary current.

• Example: If a transformer has a turns ratio of 1:10 and a primary current of 5A, the secondary

Makes in Electrical System refer to the components or devices that are used to control, protect, or distribute electrical power.
