DC circuitsQuestion 1351 of 1506

Two resistors, 150 Ω and 10 Ω, are connected in series across a 600 V supply. What is the voltage drop across the 10 Ω resistor?

  1. 40.0 V
  2. 562.5 V
  3. 300 V
  4. 37.5 V
Show answer

Correct answer: 37.5 V

Voltage divides in proportion to resistance: 600 V × 10 ÷ (150 + 10) = 37.5 V.
