When unequal resistors are connected in parallel in a circuit,

Question

BlackTom AI · Accepted Answer

When unequal resistors are connected in parallel, the key principle is that the voltage across each branch is the same, because they share the same two nodes. 
Option A says the largest resistance has the largest current through it. In parallel circuits, current through a branch is I = V/R, so a larger R yields a smaller current, not the largest. Hence this is incorrect. 
Option B claims the power generated in each resistor is the same. Power in a resistor is P = V^2/R or P = I^2R. Since R differs and the voltage across each branch is the same, P = V^2/R shows that different resistances will dissipate different amounts of power, so this is false. 
Option C states the same current always runs through each resistor. In parallel, currents split among branches according to their resistances (I = V/R). Different R values produce different currents, so this option is incorrect. 
Option D asserts the potential drop is always the same across each resistor. This aligns with the defining feature of parallel circuits: each component connected directly across the same two nodes experiences the same potential difference. Therefore, the shared voltage across all parallel branches is identical, making this statement true.
