Sample questions from this chapter

How is instantaneous electric current through a cross-section defined?
  1. The limiting rate dQ/dt ✓
  2. Charge multiplied by time
  3. Potential difference per unit charge
  4. Energy transported per unit volume
Answer: A. Instantaneous current is the limiting net charge crossing a section per unit time, I=dQ/dt.
Why not B: Current is a rate and therefore uses division by time.
Why not C: Energy per charge defines potential difference, not current.
Why not D: Current measures net charge flow, not energy density.
A steady current transports 12.0 C through a cross-section in 3.00 s. What is the current?
  1. 36.0 A
  2. 0.250 A
  3. 4.00 A ✓
  4. 9.00 A
Answer: C. I=Q/t=12.0/3.00=4.00 A.
Why not A: This multiplies charge by time rather than dividing.
Why not B: This takes time divided by charge.
Why not D: This subtracts the numerical time from charge.
What is the equivalent resistance of 4.00 Ω and 6.00 Ω connected in parallel?
  1. 2.40 Ω ✓
  2. 10.0 Ω
  3. 5.00 Ω
  4. 0.417 Ω
Answer: A. R_eq=R₁R₂/(R₁+R₂)=24.0/10.0=2.40 Ω.
Why not B: This is their series resistance.
Why not C: The arithmetic mean cannot be a parallel equivalent because it exceeds the smaller branch.
Why not D: This is 1/4.00+1/6.00, which equals reciprocal resistance and still requires inversion.
