Multiple choice general knowledge Resistance of resistors in series will be? 1/(R1+R2+R3+..........) R1R2R3......../R1+R2+R3+...... R1+R2+R3+.......... Infinity Reveal answer Fill a bubble to check yourself C Correct answer Explanation In series circuits, resistances add directly (Rtotal = R1 + R2 + R3 + ...). Current must flow through each resistor sequentially, so the total resistance is the sum of all individual resistances.
