$$R_T = 100 + 220 = 320\Omega$$
): The voltage across each branch is equal to the source voltage ( Common Calculation Guide (The "Answer Key" Logic) pltw 1.2 3 answer key
PLTW Activity 1.2.3 is designed to solidify student understanding of electrical theory. In the context of the POE curriculum, this activity usually requires students to calculate theoretical values for voltage, current, and resistance within various circuit configurations and then verify these values using physical components (resistors, power sources, and multimeters). $$R_T = 100 + 220 = 320\Omega$$ ):
The activity is divided into two primary sections: and Parallel Circuits . Mastery of these concepts is foundational for subsequent units on digital electronics and control systems. Mastery of these concepts is foundational for subsequent
Because voltage is constant across each branch: $$I_R1 = 12V / 100\Omega = 0.12A$$ $$I_R2 = 12V / 220\Omega \approx 0.0545A$$
