Manga Guide
- Voltage: difference in potential
- AMP: unit representing electrical current
- current: amount of electricity flowing through electrical line
- watt: unit representing electric power (consumed power)
- power (W) = voltage(V) x current(A)
- A = W/V
- Safety Breakers in the box thingy with switches are used to stop when there is too much electricity flowing through
- Rated Current: value determined for normal electrical outlet
Chapter 2 Arduino
- Anode is the positive side and cathode is the negative side.
- Resistance is how easy or how difficult the current can flow. this is determined by resistors that resist current. It can be like a pipe that lets a lot of water through (low resistance) or very little water (low Resistance)
- Ohm’s Law
- voltage difference in volts (V) = current in amps(I) x Resistance in ohms(R)
- Can be used to figure out which resistor value to use by solving for R
- R = V/I
- A common power rating for resistors is 1/8 of a watt (abbreviated as W, milliwatts as mW)
- Power in watts(P) = IV
