Circuitry

Question 1

What is a circuit?

Answer 1

• A circuit is a system of conductors and components forming a complete path for current to travel.

Question 2

What is Voltage?

Answer 2

• 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).

Question 3

What is Current?

Answer 3

• Current is the flow and rate of electrons in a circuit, measured in Amps (A).

Question 4

What is Resistance?

Answer 4

• Resistance is the opposition of current flow, measured in Ohms (Ω).

Question 5

What does Ohm’s Law state?

Answer 5

• 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.

Question 6

What is a Series Circuit?

Answer 6

• 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.

Question 7

What is a Parallel Circuit?

Answer 7

• 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.
