Description

Compared to the amount of electric current in the filament of a lamp, the amount of current in the connecting wire is The same Several light bulbs are connected in a circuit. When the switch is closed, All bulbs light at once As more lamps are put into a parallel circuit, the overall current in the power source Increases When otherwise identical light bulbs are connected in a combination circuit, the brightest bulb will be the bulb Having the most current flowing through it

The current through a 10.0 ohm resistor connected to a 120.0 V power supply is 12A A 4-ohm resistor is connected in series with a 4-ohm resistor. This combination produces an equivalent resistance of 2 ohms Two 200-ohm resistors in series give an equivalent resistance of 400 ohms Two 200-ohm resistors in parallel give an equivalent resistance of 100 ohms Compared to the resistance of two resistors connected in series, the same two resistors connected in parallel have Less resistance A 10.0 ohm resistor has a 5.0 A current in it. What is the voltage across the resistor? 50 V When a 20.0 V battery is connected to a resistor, the current through the resistor is 2.0 A. What is the resistor's value? 10 ohms

Three resistors, 1-ohm, 2-ohm, and 3-ohm are connected in series. Their equivalent resistance is 6 ohms

A circuit is made containing a battery and a single resistor. Decreasing the battery's electric potential difference will cause the total current in the circuit to Increase When two lamps are connected in series to a battery, the total electrical resistance that the battery senses is More than the resistance of either lamp As more and more cells are added in parallel to a circuit containing a single light bulbs, the brightness of the bulb Does not change If 5 identical bulbs are connected in parallel and one bulb goes out, the other bulbs Remain unchanged When a pair of 1-ohm resistors are connected in series, their combined resistance is 2 ohms, and when in parallel, ½ ohm A circuit is made containing a battery and a single resistor. Decreasing the battery's electric potential difference will cause the total resistance of the circuit to Remain the same The same circuit relationships that are true for resistors are true for light bulbs. True A single light bulb is connected to a battery. Which of the following would cause the bulb to shine brighter? Increase the voltage of the battery and increase the current through the bulb When two lamps are connected in parallel to a battery, the total electrical resistance that the battery senses is Less than the resistance of either lamp https://quizlet.com/11823452/3-physics-practice-questions-chapter-23-flash-cards/ https://quizlet.com/80788047/qs-13-flash-cards/ https://quizlet.com/8724994/physics-final-flash-cards/...
