Circuitry Flashcards
1
Q
What is a circuit?
A
- A circuit is a system of conductors and components forming a complete path for current to travel.
2
Q
What is Voltage?
A
- Voltage is the potential difference between different parts of a circuit (also described as the amount of electrons in a circuit), measured in Volts (V).
3
Q
What is Current?
A
- Current is the flow and rate of electrons in a circuit, measured in Amps (A).
4
Q
What is Resistance?
A
- Resistance is the opposition of current flow, measured in Ohms (Ω).
5
Q
What does Ohm’s Law state?
A
- Ohm’s Law states that voltage (V) equals current (I) multiplied by resistance (R): V = I × R.
- Voltage is proportional to current. As one goes up, so does the other.
- Voltage is also proportional to resistance. As one goes up so does the other.
- Current is inversely proportional to resistance. As one goes up, the other goes down.
6
Q
What is a Series Circuit?
A
- In a series circuit, the components are connected end to end, creating a single pathway for the current to flow.
- If one component fails, the entire circuit will be interrupted.
7
Q
What is a Parallel Circuit?
A
- In a parallel circuit, the components are connected in separate branches, allowing the current to have multiple pathways to flow.
- If one component fails, the others continue to work independently.
