Week 8¶
Vocabulary¶
I have used ChatGPT for generating the correct definationsof certain terms and then edited it accordingly. (Credit goes to AI!!)
- Electricity/Electron Flow:
Electricity is the flow of tiny particles called electrons through a conductor like a wire. It powers many of the devices we use every day.
- AC vs DC :
AC stands for Alternating Current, where the flow of electricity periodically changes direction. DC stands for Direct Current, where electricity flows steadily in one direction. The symbol for AC is a wavy line, and for DC it’s a straight line.
- Electronics Circuit:
An electronics circuit is a path for electricity to flow through various components like resistors, capacitors, and transistors, allowing them to perform specific functions.
- Ohm’s Law:
Ohm’s Law states that the voltage across a conductor is directly proportional to the current flowing through it, given a constant resistance.
- Conductance:
Conductance is the measure of how easily electricity flows through a material. The higher the conductance, the easier it is for electricity to pass through.
- Resistance:
Resistance is the property of a material that opposes the flow of electric current. It’s measured in ohms (Ω).
- Voltage:
Voltage is the difference in electric potential between two points, which causes electric current to flow. It’s measured in volts (V).
- Current:
Current is the flow of electric charge through a conductor. It’s measured in amperes (amps).
- Load:
A load is a component in an electrical circuit that consumes power, such as a light bulb or a motor.
- Polarity:
Polarity refers to the positive or negative orientation of an electrical voltage.
- Anode & Cathode:
An anode is the positively charged electrode, and a cathode is the negatively charged electrode in a device like a battery or diode.
- Parallel vs Series circuit arrangements:
In a parallel circuit, components are connected in branches, offering multiple paths for current. In a series circuit, components are connected end-to-end, offering a single path for current.
- Resistor:
A resistor limits the flow of current in a circuit. It’s measured in ohms (Ω), and its symbol is a zigzag line.
- Capacitor:
A capacitor stores electrical energy temporarily. It’s measured in farads (F), and its symbol looks like two parallel plates.
- Diode:
A diode allows current to flow in only one direction. Its symbol is an arrow pointing in the direction of flow.
- LED:
A Light Emitting Diode emits light when current flows through it. It’s commonly used in indicators and displays.
- Transistor:
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
- Regulator:
A regulator is a circuit that maintains a constant output voltage irrespective of changes in input voltage or load conditions.
