What statement is true concerning the electrical diagram shown in figure "B" of the illustration? Illustration EL-0019
β’ Difference between series and parallel resistor connections in DC circuits β’ How voltage behaves in parallel vs series circuits (same vs divided) β’ How to compute total resistance for series vs parallel (qualitatively, not the formula)
β’ Look at where the tops and bottoms of R1, R2, and R3 are connected. Do they all share the same two nodes, or are they connected one after another? β’ If you measured voltage with a meter across each resistor, would the meter be connected to the same two circuit points each time, or to different points along a chain? β’ In the arrangement shown, would the total circuit resistance be greater than any individual resistor, or less than the smallest resistor?
β’ Identify whether R1, R2, and R3 share both endpoints (common top node and common bottom node). β’ Decide whether in this configuration the voltage across each resistor must be the same or can be different. β’ Recall that in a series circuit resistances add directly (R_total = R1 + R2 + R3), but in a parallel circuit the total resistance is less than the smallest branch resistance.
