There are negative and positive charges. Like charges repel while opposite charges attract. Materials can be rubbed or brushed to transfer charge to them.  Lightning is the result of movement of electrical charge from the clouds to the ground. Current electricity is the result of flowing charge. Cells convert chemical energy into electrical energy. Electrical energy is hazardous and safety precautions should be observed when it is used.
