(2) Five identical bulbs (numbered 1-4) are arranged as shown (a) Rank the brightness of from BRIGHTEST to DIMMEST (b) What would happen to the brightness of Bulb 1 if the wire was cut between bulbs 2 and 3? Explain 5 (c) You have 3 bulbs, some wire, and a battery. Draw two circuits: One circuit must have have all 3 bulbs be brighter than the ones in the other circuit (3) Find the the current and potential difference for...
Problem 4: Bulbs A and Cuse 40 W of power when conmected to a 120VE standard 120-volt outler. BulbsB and D use 60 W uhen Bulbs A and C connected directly to voltage source. to a standard outlet. A student connects bulhs A and B in series to a standard outlet and bulbs C and D in parallel to a standard ouclet as shown Series circuit 6o w Bulbs B and D connected directly to voltage source. Parallel circuit (a)...
The power supply is a 6.0 V battery. The resistance of bulbs A, B, and C is 2.00Q The resistance of bulbs D, E, and F is 3.00 1. What is the current through bulb D if all bulbs are lit? 2. What is the voltage drop across bulb B if all bulbs are lit?
Current and Resistance 1. Rank in order from brightest to dimmest the light bulbs in the figure below. exceeds 2A. The only material you have access to that you can build the fuse out of has a max current density of 375A/cm2 (this means it will melt if the current density is larger than this value). What is the diameter of a wire made from this material that will work for your job? 3. You are doing an experiment in...
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...
Question 1: The bulbs in the circuit shown below are all identical. Treat the battery as ideal. For each pair of bulbs listed below, indicate which bulb will be brighter. If the two have the same brightness, state that explicitly. In each case, please explain your reasoning • A and C. (Which is brighter and why?) • C and D. . E and F D А B E G H F
4. Consider the identical light bulbs (e) in the circuit to the right. Circuits 1, 2, 3, 4 are series circuits". I? 2 Circuits 5, 6, and 8 are "parallel circuits". 4 Some circuits have one battery, others have two batteries. 6 Now close the switch. Using the "brightness" of the bulb in the simple circuit 1 as the standard for normal" brightness, answer the following questions by specifying the circuit(s) number(s) 5 7 (a) Which circuits had bulbs that...
of the following correctly ranks the currents flowing through the bulbs? A. All bulbs have the same current flowing through them. B. The current through 1 is largest, 2 next largest, 3 next largest and 4 smallest. C. The current through 1 is largest. 2 is the same as 3, and each is smaller than 1. 4 D. The current through 1 and 4 is the same. 2 is the same as 3, and each is smaller is smallest The...
