question 7

Multiple Choice

A series circuit consists of a 10 $\Omega$ resistor, a 20 $\Omega$ resistor, and a 30 $\Omega$ resistor. The circuit is connected to a 120 V source. If the voltage across the 10 $\Omega$ resistor measures 20 V and the voltage across the 30 $\Omega$ resistor measures 60 V, how much voltage should be measured across the 20 $\Omega$ resistor?

• A) There is not enough information given to solve this problem.
• B) 120 V
• C) 40 V
• D) 10 V
