How is the value of the current affected? / I: 2::I The current increases by a factor of 2 \\ / I: 22:::I The current decreases by a factor of 1/4 \\ / I: :2: The current decreases by a factor of 1/2 \\ / I: 22:::I The current increases by a factor of 4 \\ Question 3 (1 point} Which example is most likely powered by direct current? II: 2:] a household electric frying pan II: 2:] the lamp in a kitchen ceiling II: 2:] the glevc-compartment light in an automobile .' 2\\. - - v I. .I a bathroom ceiling fan Question 4 (1 point} The devices and outlets in each circuit in a household are wired in parallel. The main reason for this is O plugging in more devices decreases the total resistance on the circuit I7 2::I connecting the devices in parallel is safer than if they were in series I7 2::I unplugging a device does not affect the other devices on the circuit / I: 2_2:I plugging in more devices increases the total resistance on the circuit \\ Question 5 (1 point} A student constructed a simple electric circuit where two light bulbs were connected in parallel. The circuit power source was a 6.0-V cell. One of the light bulbs had a resistance of 25 Q, and the other had a resistance of 50 Q. What was the combined resistance of the light bulbs in this circuit? (2::I 25 Q \\ (2::I 41 Q \\ I722:::I 17 Q \\ (2::I 75 Q \\ Question 6 (1 point) A student experiments with three identical light bulbs. First, he places two of them in series in a circuit. Then he adds a third bulb in series with the other two. What is the effect of adding the third bulb? O Each bulb in the circuit will glow more brightly, and the total resistance of the bulbs in the circuit will decrease O Each bulb in the circuit will glow less brightly, and the total resistance of the bulbs in the circuit will decrease Each bulb in the circuit will glow more brightly, and the total resistance of the bulbs in the circuit will increase Each bulb in the circuit will glow less brightly, and the total resistance of the bulbs in the circuit will increase Determine whether the next six statements are true or false.

O True False Question 11 (0.5 points) The effect of adding an extra bulb in parallel to a bulb already in a circuit increases the circuit's total resistance. True FalseQuestion 12 (0.5 points) The effect of adding an extra bulb in series with a bulb already in a circuit increases the circuit's total resistance True False Question 13 (3 points) Match each symbol with the appropriate term listed. 1. battery 2. switch 3. joined wires 4. resistor 5. lamp 6. ohmeter Question 14 (1 point) A string of 24 Christmas lights didn't work. Jane replaced the bulbs one at time ar found that after replacing the seventh bulb, the lights all lit up. The lights were connected in __i__ to a 120 V outlet. Each bulb had a __ii__ V potential difference across it when the string was on. The statements above are completed correctly by the following information: series, 5 O parallel, 120 O parallel, 5 series, 120 Question 15 (1 point) Calculate the voltage of a battery made up of four 3.6-V lithium-ion cells connected in series. 15.0 V 10.8 V O 0.90 V 14.4 VQuestion 16 (1 point) A 100-W light bulb in a receptacle is supplied with electricity by a residential 120-V circuit.
