- resistors aren't always the exact value you want it to be so sometimes you have to combine resistors.
- 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.

- Resistance in electronics is a lot like friction in mechanical systems; it puts a stop on electrons as they move through materials.
- resistors are components that control amounts of resistance for electronic circuits.
- resistance is a measure of an object's opposition to the flow of electrons.
- resistance makes it possible to generate heat and light, restrict the flow of electric current, and ensures that the correct voltage is supplied to the device.
- resistance depends on several factors like material, cross-sectional area,length, and temperature.
- "R" is used to represent resistance in an electronic circuit.
- resistance is measured in ohms.
- kilohms is thousands of ohms and megohms is millions of ohms.
- LEDs eat up current and drain as much as they can, but can burn themselves out if they draw too much current and a resistor limits the amount of current sent to the LED.
- resistors also protect sensitive components such as a transistor.
- resistors come in two basic functions, fixed and variable.
- a fixed resistor supplies a constant, factory determined resistance.
- the actual resistance of a fixed resistor may vary up or down.(ex: a 1,000 ohm resistor with a 5% tolerance could range from 950-1050 ohms)
- high precision resistors come within a 1% of their nominal value.
- standard precision resistors can vary from 2% to 20% of their nominal values.
- a variable resistor also known as a potentiometer allows you to continually adjust the resistance from zero ohms to factory determined maximum value.

- electron flow can be induced by moving a wire near a magnet and is called electromagnetic induction.
- alternating current is constantly changing and it's strength cannot be described with a single number.
- a common way in which to describe the variations is to look at a waveform or the pattern of the current over time.
- instantaneous current is the strength of the current at a single point in time.
- peak current is the magnitude of the current at its highest and lowest points.
- when the change in electron flow makes a complete loop it is called a cycle.
- the number of cycles per second in ac is known as frequency and is measured in hertz.
- AC is usually generated at 13,800 volts and then stepped up for transmission across long distances.
- when it reaches its destination, it is stepped down to 240 volts or 120 volts for distribution to homes and businesses.
- heaters, lamps, hair dryers, and electric razors are some electrical devices that use 120 volts AC directly.
- clothes dryers use 240 volts AC directly from a special wall outlet.
- many electronic devices like laptops require a steady DC supply.
- if you're using AC to supply power an AC-to-DC adapter is required to convert the AC power to DC power.
- solar cells produce a small voltage when you shine light on them.
- the voltage of solar cells is constant no matter how much light you shine on them.
- conventional current is the flow of a positive charge from positive to negative voltage and is just the reverse of real electron flow.
- In AC current the current is constantly reversing direction.
- a light bulb converts electrical energy into heat energy.
- voltage is sometimes called voltage drop, potential difference, or potential drop.
- a fundamental law of physics is that energy cannot be created or destroyed; it can only change form.
