transformer is static device which transfer energy form one place to other place at a time of energy transferring mode device get saturated and heated up for that AIR GAP is necessary for cooling as well as lenkage of flux for addy current purpose...

When batteries are connected in series the voltage increases but the current remains unchanged, how can this be? When you consider ohm's law. i.e. If voltage increases, current increases, providing resistance remains the same.
