No energy is lost in an ideal transformer, so the output power pout from the secondary coil equals the input power pin to the primary coil. suppose a neighborhood transformer delivers 210 a at 120 v. what is the current in the 1.4×104 v line from the substation?

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
