Resistors and Ohm's Law Video Lessons

Concept

# Problem: Imagine a single-loop circuit with a battery, and three resistors R1, R2, R3 connected in series. Resistance is ignorable except for the resistors. Resistors are ohmic. Answer the following questions a. Which (if any) physical quantity- among resistance R, current I, and voltage V must be the same for the three resistors? b. How are R, I, and V related for each resistor in this circuit? Answer with an equation involving these three quantities.

###### FREE Expert Solution

a.

The resistors are in series.

This implies that the same current will be flowing through the circuit.
