In a step-down transformer, primary coil will have more current.
False
A transformer is a device that changes an alternating potential difference from one value to another value by using the principle of electromagnetic induction. A transformer consists of a soft iron coil with two coils wound around it which are not connected to one another.
A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up transformer. Conversely, a transformer designed to do just the opposite is called a step-down transformer. Step down transformer is used to step down the voltage. Since there is no power loss during transmission, the power is same in primary and secondary coils. Thus the coil having a lower voltage will have a higher current. Hence, current in the secondary coil is more. So, the given statement is false.
