  1. 1. The SI unit of electric current is the:
    • (a) volt
    • (b) watt
    • (c) ampere
    • (d) ohm
  2. 2. Ohm's law is expressed as:
    • (a) R = VI
    • (b) V = I/R
    • (c) I = VR
    • (d) V = IR
  3. 3. The SI unit of resistance is the:
    • (a) joule
    • (b) ohm
    • (c) volt
    • (d) ampere
  4. 4. Two resistors of 3 Ω and 6 Ω in parallel give an equivalent resistance of:
    • (a) 18 Ω
    • (b) 4.5 Ω
    • (c) 2 Ω
    • (d) 9 Ω
  5. 5. Define one ampere.
  6. 6. Why is the resistance of a thick wire less than that of a thin one of the same material and length?
  7. 7. Compare series and parallel combinations of resistors.

  1. 1. (c) ampere — Current is measured in amperes (A).
  2. 2. (d) V = IR — V = IR at constant temperature.
  3. 3. (b) ohm — Resistance is measured in ohms (Ω).
  4. 4. (c) 2 Ω — 1/R = 1/3 + 1/6 = 1/2, so R = 2 Ω.
  5. 5. One ampere is the current when one coulomb of charge flows through a point in one second.
  6. 6. A larger cross-sectional area means lower resistance, since R = ρl/A.
  7. 7. In series, the same current flows through all resistors, the voltage divides among them, and the equivalent resistance R = R₁ + R₂ + … (largest). In parallel, the same voltage is across all resistors, the current divides, and 1/R = 1/R₁ + 1/R₂ + … (smallest). Household appliances are connected in parallel so each gets the full voltage and can be switched independently.
