Four identical bulbs, each with a filament resistance of 65 Ω, are connected to a 30-V battery as shown in the diagram below. S1, S2, and S3 represent switches. (a) If S1 and S2 are closed while S3 is open, what is the current through each bulb? (b) If S3 is closed while S1 and S2 are open, what is the current through each bulb?
Two different light bulbs (RD> RE) are connected as shown below. If the internal resistance of the battery is not considered negligible (r ≠ 0), what happens to the current through the bulb D when the switch is closed? a) it decreases somewhat b) it increases significantly c) it stays the same d) it increases somewhat e) it decreases significantly S CS2 CS1 D E
Four identical bulbs, each with a filament resistance of 132 Ω, are connected to a 35-V battery as shown in the diagram below. S1, S2, and S3 represent switches. (a) If S1 and S2 are closed while S3 is open, what is the current through each bulb? bulb 1 bulb 2 bulb 3 bulb 4 (b) If S3 is closed while S1 and S2 are open, what is the current through each bulb? bulb 1 bulb 2 bulb 3 bulb...
Two light bulbs are connected in parallel, and then connected to a battery, as shown in Fig. 4.51(a). You observe that bulb 1 is twice as bright as bulb 2. Assuming that the brightness of a bulb is proportional to the power dissipated in the bulb’s resistor, which bulb’s resistor is larger, and by what factor? The bulbs are now connected in series ,as shown in Fig.4.51(b). Which bulb is brighter, and by what factor? How bright is each bulb...
Question 5 1 pts Three identical light bulbs are connected to a battery as shown in the circuit below. After the switch Sis closed, S L M light bulb N grows brighter. light bulb L grows dimmer. the power supplied by the battery increases. the current through the battery decreases.
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
A 12-volt battery is connected to two light bulbs, as drawn in Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2 has resistance 6 ohms. The battery has essentially no internal resistance, and all the wires are essentially resistanceless, too. When a light bulb is unscrewed, no current flows through that branch of the circuit. For instance, if light bulb 2 is unscrewed, current flows only around the lower loop of the circuit, which consists of...
please answer both if possible thank you b. Three electric bulbs are connected in circuit with the 120 V battery as shown in the circuit diagram below . With the switch open (a) The manufacturer specifications for the cach bulb are 120V, 40W; 120V, 20W and 120V, 60W respectively. Using this specifications (means apply a 120 V to calculate the resistance of the bulbs), calculate the resistance of each bulb, note that the resistance of the bulbs remain constant. (R-360...
