Current | a movement of electrical charges around a closed path or circuit. |
Resistance | Opposition to current. Unit is the ohm. |
Digital | A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values. – lines that are same distance apart and will never meet. |
Bread board | A circuit board for wiring temporary circuits, usually used for prototypes or laboratory work. |
Ohm | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. |
Digital Multimeter | A piece of test equipment used to measure voltage, current, and resistance in an electronic circuit. |
LED | Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting. |
Conventional Current | The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential, which is in the opposite direction of electron flow. |
Ohm's Law | In electric circuits, V = IR |
Fuse | A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value. |
