A Parallel Circuit Consists of a 10 $\Omega$ Resistor, a 20 $\Omega$

question 10

Multiple Choice

A parallel 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 30 $\Omega$ resistor is 120 V, how much voltage will be measured across the 10 $\Omega$ resistor?

• A) There is not enough information given to solve this problem.
• B) 0 V
• C) 80 V
• D) 120 V

Definitions:

Alternative Hypothesis

In statistical hypothesis testing, a statement that contradicts the null hypothesis, suggesting that there is a statistically significant difference between observed data and the expected outcome under the null hypothesis.

Two-tail Test

A statistical test in which the critical area of a distribution is two-sided and tests whether a sample is either greater than or less than a range of values.

Nominal Data

Data that represents categories with labels or names, where the order of the categories is not meaningful.

Z-test

A statistical test used to determine whether two population means are different when the variances are known and the sample size is large.
