800 V

0.80 V

0.8 V

0.0128 V
Question 9: Using V = I × R, if voltage is 9.0 V and resistance is 560 Ω, what is the current? (Calculate or test in sim.)(3 points)

5040 mA

0.016 mA

16.07 mA

62.2 mA
Question 10: Overall, Ohm's Law shows that current (I) is:(3 points)

Always the same as voltage.

Directly proportional to voltage (V) and inversely proportional to resistance (R).

Not related to voltage or resistance.

Inversely proportional to voltage and directly proportional to resistance.

Answer 1

Q8: 0.80 V (3.2 mA = 3.2×10⁻³ A; V = I·R = 3.2×10⁻³ × 250 = 0.8 V)

Q9: 16.07 mA (I = V/R = 9.0 / 560 = 0.01607 A = 16.07 mA)

Q10: Directly proportional to voltage (V) and inversely proportional to resistance (R).
