Across
  1. 3. a cylindrical coil of wire acting as a magnet when carrying electric current.(solenoid)
  2. 6. the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.(ohm)
  3. 9. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.(electrons)
  4. 10. substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.(conduct)
  5. 11. the SI base unit of electric current, named after French mathematician and physicist André-Marie Ampère, considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted(amp)
  6. 12. a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.(electromagnet)
  7. 13. An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.(current)
  8. 15. Atom with more electrons than protons.(negative)
  9. 16. a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.(electricity)
Down
  1. 1. the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.(volt)
  2. 2. an instrument for measuring electric potential in volts.(voltmeter)
  3. 4. the process of insulating material from transferring heat between the materials that are in thermal contact. (insulate)
  4. 5. an instrument for measuring electric current in amperes.(ammeter)
  5. 7. a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.(magnet)
  6. 8. In an atom, a positive charge occurs when an atom has more protons than electrons. The proton is what determines its positive charge.(positive)
  7. 14. composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.(circuit)
