Question 3: The circuit below consists of 3 identical bulbs. Initially, the switch is closed and all the bulbs are the same brightness. What will happen to the brightness of bulb A if the switch is opened? Justify your answer switch А B C
please explain! In the circuits below, all bulbs are identical, and all batteries are ideal and identical. A B 1. Consider the circuit at right. Note that the middle battery is not connected in the same way as the other two. Rank bulbs A-C according to brightness, from largest to smallest. If any bulbs are equal in brightness or if any bulbs are not lit, state so explicitly. Explain. с
In the circuits below, all bulbs are identical, and all batteries are ideal and identical. 2. Consider the circuit at right. a. 2 Is bulb 1 brighter than, dimmer than, or as bright as bulb 2? Explain. A B b. Is the current through battery A greater than, less than, or equal to the current through battery B? Explain.
Batterles and Bulbs-Bulb Brightness"1 Identical batteries are connected in different arrangements to the identical light bulbs Rank from brightest to least bright these items on the basis of bulb brightness. Brightest 1 2. 3. 5 Least Bright Or, all bulbs have the same brightness. Please carefully explain your reasoning I
Two batteries, a capacitor, and two light bulbs are connected by wires. The batteries have a potential difference emf, the capacitor has capacitance C, and the bulbs have resistance R. Initially the capacitor is uncharged and the switch has been closed. A)Write down the three loop rules and the node rule for this circuit and label the currents on the picture. B) Find the initial currents running through each bulb. C)What is the current running through each bulb a long...
PLEASE ANSWER BOTH:) Question 3: Which of the following circuits of identical light bulbs and batteries would draw the greatest current from the battery? @ (A) (B) (C) (D) (E) Question 4: A circuit of ohmic resistors is shown in the diagram to the right. Which of the following is the current flowing through the resistor Ri? Y A) 4 A B) 2 A C) 1 A D) 0.5 A E) O A XW R2 = 202 R2 = 2012...
Three identical light bulbs labeled A, B and C are connected to a battery as shown in the circuit below. When the switch is closed, which of the following statements is true about the currentthrough the light bulbs? A. No current flows through bulbs B and C because the B/C loop does not contain a battery. Only A has a current running through it. B. The current through A is equal to the sum of the currents through B...
Four identical light bulbs are in a circuit as shown. After I throw the switch, what happens to the brightness of the bulbs A, B, and C? Image size: SML Max A Select the correct answer O All stay the same O All get brighter A gets dimmer, B and C get bright Your Answer O A gets brighter, B and C get dimmer O A stays the same, B and C get dimmer O All get dimmer
Identical light bulbs each in a socket can be connected to identical batteries in three different ways (A, B, or C), as shown in the figure. The ranking (from lowest to highest) of Bulb A's voltage is Bulb A Butb A Butb A C<A B
