1 answer

Here are the answers to your questions:

Question 1: What does the size of a current depend upon?

  • Answer: voltage

Question 2: What is the rate at which charges pass through a given point called?

  • Answer: current

Question 3: What is the current if the voltage is 20 V and the resistance is 10 Ω?

  • Answer: 2 A (using Ohm's Law: I = V/R)

Question 4: What are the tiny particles that make up matter?

  • Answer: atoms

Question 5: What is the potential difference between two points in a circuit called?

  • Answer: voltage

Question 6: AC stands for

  • Answer: alternating current

Question 7: In AC, the flow of electrons

  • Answer: keep switching direction

Question 8: DC stands for ____ and is used in batteries.

  • Answer: direct current

Question 9: What type of circuit are these models representing?

  • Answer: series (if the circuit has a single path) or parallel (if there are multiple paths). The exact answer would depend on visual context.

Question 10: What type of circuit are these models representing?

  • Answer: series circuit or parallel circuit (similar to Question 9)

Question 11: What type of circuit does this model represent?

  • Answer: series circuit or parallel circuit (depends on the model shown)

Question 12: What type of circuit does this model represent?

  • Answer: closed series (if one single path is complete) or closed parallel (if multiple paths are complete).

Question 13: The current in a resistor is 5.0 A, and its resistance is 60 Ω. What is the voltage?

  • Answer: 300 V (using Ohm's Law: V = I * R = 5.0 A * 60 Ω)

Question 14: The current in a resistor is 3.0 A, and its resistance is 10 ohms. What is the voltage developed in the resistor?

  • Answer: 30 V (using Ohm's Law: V = I * R = 3.0 A * 10 Ω)

Question 15: The unit(s) for current is

  • Answer: Amps
