- If you know that a light bulb has a certain amount of resistance and you place a resistor in series with the light bulb to limit the current, you'll need to know that the total resistance of the two components before you can calculate the current passing through them.
- when you connect two or more resistors in series, you must connect them end to end, so that the current passes sequentially through each resistor.
- To find the total resistance you simply have to add the resistor values. EX. 22Ω+33Ω = 55Ω
- When adding the resistor values you must also be careful with the values. EX. 22kΩ+33Ω= 22,033Ω
- When you combine to resistors in parallel, you connect both sets of end together so each resistor has the same voltage.
- When you do that you provide two different paths for current to flow.
- The reason for creating a parallel is to decrease the overall resistance.
- Soldering is the method you use to make semi-permanent connections between components as you build a circuit.
- When soldering you use solder and a soldering iron to create a solder joint which provides a conductive physical joint.
- The lead content in 60/40 rosin core solder may pose a health hazard if not handled correctly.
-A multimeter measures AC and DC voltages, resistance, and current when you want to explore whats going on in the circuit.
- If you don't keep the circuitry, components, and other parts of your electronics clean, they may not operate as they should be.
-Anti-static wrist straps prevent electrostatic discharge from damaging sensitive electronic components.
-Safety glasses are needed to protect your eyes from flying pieces of wire, sputtering solder, and possible exploding electronic parts.
- Burns and other mishaps may occur when working with electronics so a first aid kit nearby is recommended.
