Across
  1. 5. Materials in which electric current does not flow freely, High resistivity materials are those used as electrical insulators.
  2. 7. The work done by a source in moving a unit charge passing through a component.
  3. 11. it is an imbalance of electric charges within or on the surface of a material or between materials.
  4. 12. a current that flows in a single direction only.
Down
  1. 1. it is a tool used to measure magnitude and direction of an electric current in an electrical circuit.
  2. 2. Used to measure the e.m.f of a dry cell of the p.d. across a component.
  3. 3. a current that changes direction frequently.
  4. 4. the International System of Units (SI) unit for electric potential, electric potential difference (voltage), and electromotive force.
  5. 6. the charge passing a point per unit time.Conventional current, from positive to negative and that flow of free electrons is from negative to positive.
  6. 8. the potential difference across it divided by the current flowing through it.
  7. 9. it is the International System of Units' unit of electric current.
  8. 10. A property of a unit of matter that describes how many more or fewer electrons than protons it contains.
