ID: B 17. Two lamps, one with a thick filament and one with thin filament, are in series. Which is true? A. The current is greater with the thick filament lamp. B. The current is greater with the thin filament lamp. C. The total voltage is the sum of the voltages in both. D. Current is the same in both lamps.. 18 . As more resistors are added to a circuit in parallel, the total resistance the total current , and the total power output of the circuit A. decreases, increases, increases D. increases, decreases, increases B. increases, decreases, decreases E. None of these. C. decreases, increases, decreases True/False Indicate whether the statement is true or false. If false, correct the underlined part. 19. When resistors are connected in series, a 2 S resistor has less current flowing through it than a 1 2 resistor. Same 20. As more lamps are put in parallel in a circuit, the overall current increases. 21. In a parallel circuit, the total resistance is the same throughout the whole circuit. 22. In a parallel circuit, the total resistance is equivalent to the sum of all the resistors. 23. When resistors are arranged in parallel, their overall resistance is less than that of the smallest resistor. move
