| Question | Answer |
|---|---|
| circuit | A closed path followed or capable of being followed by an electric current. |
| Conductor | A material or an object that conducts heat, electricity, light, or sound. |
| Ion | An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. |
| Insulator | A material that insulates, especially a nonconductor of sound, heat, or electricity. |
| ohm law | electric current is directly proportional to voltage and inversely proportional to resistance; |
| resistance | A force, such as friction, that operates opposite the direction of motion of a body and tends to prevent or slow down the body's motion. |
| voltage | A measure of the difference in electric potential between two points in space, a material, or an electric circuit, expressed in volts. |
| static change | A form of charge, designated positive, negative, or zero, found on the elementary particles that make up all known matter. |
| current | A flowing movement in a liquid, gas, plasma, or other form of matter, especially one that follows a recognizable course. |
| electric field | The distribution in space of the strength and direction of forces that would be exerted on an electric charge at any point in that space. |
| electric force | The force exerted by stationary objects bearing electric charge on other stationary objects bearing electric charge. |
| power | The source of energy used to operate a machine or other system. |
| series circuit | An electric circuit connected so that current passes through each circuit element in turn without branching. |
| parallel circuit | circuit that has more than one path for electric current to follow |
