Study Notes
Understanding Electronic Circuits and Current
- Complex circuits typically have at least one DC power supply, and some may have multiple power supplies.
- Typical power supply voltages are +3.3V, +2.5V, or +1.8V, with a full layer of the circuit board dedicated to the main power supply.
- Passive components in a circuit, like resistors and capacitors, don't require external power and reside in the current path.
- Active components in a circuit, like diodes and transistors, require external power and can inject power into the circuit.
- Ground plane is abbreviated as GND, and the term "printed circuit board" is often abbreviated as PCB.
- An analog circuit has continuously varying current or voltage, while a digital circuit has defined values representing zeros and ones.
- High-end CPUs for computers have circuits made up of billions of transistors.
- Current is the flow of electric charge, and it is measured in amperes (A) or amps.
- Current is calculated using Ohm's Law (I = V/R) and can be used to calculate power (P = I * V).
- Direct current (DC) is a constant flow of electric charge in one direction, while alternating current (AC) constantly changes directions.
- Current plays an important role in electromagnetism, described by Ampere's law, used in electric motors.
- Ohm's Law (V = I * R) describes how current flows through a resistance when different electric potential (voltage) is applied.
