question 1) A schematic diagram is a representation of a circuit by using symbols to represent the components.

question 2) A resistor is a electronic component that slows down the flow of electricity in a circuit.

question 3) A rectifier diode let electricity flow in only one direction.

question 4) The difference between a polarized capacitor and non-polarized capacitor is that a polarized capacitor can only be put on in a certain direction relative to the circuit, but a non-polarized capacitor can be put on in any direction relative to the circuit.

question 5) A led is a Light Emitting Diode.

question 6) A transistor is a electronic component that is used to switch between electrical currents by using small pulses of electricity.

question 7) A relay is a mechanical switch that uses magnets to activate the switch.

question 8) Analog input is on a much broader range taking in more info, while on the other hand digital input uses 1 and 0 for the input values.

question 9) A variable resistor is a resistor thats resistance can be changed.

question 10) A PowerSwitch Tail is used to turn on 120 volts using a low volt input.

question 11) A pull down resistor is a circuit that uses a switch that is not connected to send electricity to the rest of the components in the circuit, but when the switch is closes the electricity goes to ground.

question 12) we need to use a diode with a transistor in a circuit with a motor so that the electricity doesn't flow backwards because of the motor generating electricity.
