How many milliamps are required in the secondary coil if the primary current is 1.3 amps?

To determine the required milliamps in the secondary coil based on the primary current of 1.3 amps, we can apply the principle of a transformer, particularly considering the relationship between primary and secondary coils defined by the turns ratio.

Transformers operate under the principle of conservation of power (ignoring losses for this ideal situation). The formula relating the currents in the primary and secondary coils can be expressed as:

[ \frac{I_p}{I_s} = \frac{N_p}{N_s} ]

Where (I_p) is the primary current, (I_s) is the secondary current, (N_p) is the number of turns in the primary coil, and (N_s) is the number of turns in the secondary coil.

While the question does not provide the turns ratio or the specific voltage levels, we can still apply the information about the current directly to the basic principles of transformers. Given the primary current of 1.3 amps, one must consider the value of the turns ratio to find the secondary current in milliamps.

Without specific values for Np and Ns, the correct solution would align with the derived formula within the context of typical transformer design applications. If under conditions provided (
