Explanation
The chapter explains that: A Voltaic cell generates electricity through chemical reactions between electrodes and electrolyte. Electric iron works on the heating effect of electric current, where resistance converts electrical energy to heat. Nichrome wire offers higher resistance and is best suited for heating elements in devices like electric heaters. An electromagnet works on the magnetic effect of electric current, where a current carrying coil behaves like a magnet.
