ELECTRICITY

Fill the gaps The materials which conduct electricity are called conductors whereas those materials that can´t conduct electric current are called insulators.Electrostatics is the type of electricity that takes place in insulators.When a material is rubbed against another material, they both become charged. The material that loses electrons gets a positive charge. The material that gains electrons gets a negative charge. The change of energy produced in a cell is from electrical to thermal from gravitational to chemical from chemical to electrical from thermal to gravitational The current in a cirtuit is related to the energy of the moving charges the energy supplied by the emf the amount of moving charges the resistance of the lamp Complete below FRICTION INDUCTION CONTACT electron transfer (yes yes no yes temporary charge(yes no yes no Match each concept on the left to its description on the right voltage related to the amount of energy resistance opposition to the pass of electricity direct current it mantains the same direction alternate current it changes direction potential energy stored energy kinetic energy energy in motion emf source of energy To mark a word click its first letter then click its last.
