A 9.0 V supply is connected across a 2.0 kilohm resistor in series with a 1.0 kilohm resistor. What is the pd across the 1.0 kilohm resistor?

Answer and explanation

Correct answer: A. 3.0 V

  1. Step 1: The pd divides in proportion to resistance: . Step 2. V. Answer: 3.0 V. Why not the others: 6.0 V is the pd across the 2.0 kilohm resistor; 4.5 V assumes equal resistances; 9.0 V is the supply pd.
