Electricity demonstrates three key effects: magnetic, thermal, and chemical. Magnetic effects arise from electric currents creating magnetic fields. Thermal effects result from resistive heating, while chemical effects lead to reactions during processes like electrolysis. ;
Electricity exhibits three main effects: magnetic, thermal, and chemical. Magnetic effects involve the generation of a magnetic field by electric currents, thermal effects result in heat production through resistance, and chemical effects can trigger reactions through electrolysis. Therefore, the correct answer is Option D.
