How does the use of the Passive Voice depend on the doer of the action?
Translate paying attention to the Passive Voice.
1. Materials can be classified according to their electrical properties. 2. This method is based on the ability of a material to conduct electricity. 3. What materials are called conductors? 4. The materials that have very few or no free electrons are called insulators. 5. Electronics is defined in an English dictionary as "the study of conduction of electricity in a vacuum, in gases and in semiconductors". 6. When the cathode is heated, it emits electrons. 7. The electrons are repelled toward the plate by the negative voltage on the cathode. 8. If a negative voltage is applied to the plate, current does not flow.
