Breadboard
A circuit board for wiring temporary circuits, usually used for prototypes
Insulator
A material that does not allow current to flow when voltage is applied because of its high resistance
Current
A movement of electrical charges around a closed path or circuit.
Digital
A way of representing a physical quantity by a series of binary numbers. A digital representation can only have specific discrete values.
Conductor
Any material that allows the free movement of electric changes, such as electrons, to provide an electric current
Parallel Circuit
Circuit that has two or more branches for separate current from one voltage source
IT=I1+I2+I3
Current in a Parallel Circuit
IT=I1=I2=I3
Current in a Series circuit
Voltage
IR
Ohm's Law
In electric circuits, I=V/R
Series Circuit
One that has only one path current
Resistance
Opposition to current. Unit is the ohm
A good conductor
Outer shell is not close to full
1/RT=1/R1+1/R2+1/R3
Resistance in a parallel circuit
RT=R1+R2+R3
Resistance in a series circuit
Kirchoff's Current Law (KCL)
The algebraic sum of all currents into and out of any branch point in a circuit must equal zero
Kirchoff's Voltage Law (KVL)
The algebraic sum of all voltages around any closed path must equal the total voltage.
Nucleus
The massive, stable part of the atom that contains both protons and neutrons
