. In the experiment shown below, explain what happens to the closed clrcult on the right and explain why briefty. ண (a) When the switch S is just opened or closed: (b) Along time after switch is closed or opened:
Initially bulbs A and B in (Figure 1) are glowing. What happens to bulb B if the switch is closed? Does it get brighter, stay the same, get dimmer, or go out?
*** Problem 3 When switch S in Figure 1 is open, the voltmeter V reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter reads 1.65 A. (Note: r is internal resistance of the battery.) fr Figure 1: Assume that the two meters are ideal so they don't affect the current in the circuit. a What is the EMF, V, produced by the battery? b) What is the liternal cesistance, r, of...
In the circuit shown in the figure, bulbs A and B are glowing.Then the switch is closed. What happens to each bulb? Does itget brighter, stay the same, get dimmer, or go out? Explain.
When switch S in the figure is open, the voltmeter V of the battery reads 3.09 V . When the switch is closed, the voltmeter reading drops to 2.96 V , and the ammeter A reads 1.66 A . Assume that the two meters are ideal, so they do not affect the circuit. (Figure 1) - From that we find that emf E = 3.09 V.Find the internal resistance r of the battery.
When switch S in the figure (Figure 1)is open, the voltmeter V of the battery reads 3.13 V . When the switch is closed, the voltmeter reading drops to 2.99 V , and the ammeter A reads 1.70 A . Assume that the two meters are ideal, so they don't affect the circuit.1) Find the emf.2) Find the internal resistance of the battery.3) Find the circuit resistance R.
By what percent does the current through A change when the switch is closed? I just need Part C. I can't figure it out. Problem 28.54 For an ideal battery (r 02), closing the switch in (Figure 1) does not affect the brightness of bulb A. In practice, bulb A dims just a little when the switch closes. To see why, assume that the 1.50 V battery has an internal resistance 0.80 2 and that the resistance of a glowing...
For an ideal battery , closing the switch in the figure (Figure 1) does not affect the brightness of bulb A. In practice, bulb A dims just a little when the switch closes. To see why, assume that the 1.5 V battery has an internal resistance and that the resistance of a glowing bulb is . What is the current through bulb A after the switch has closed? By what percent does the current through A change when the switch...
After a very long time, the capacitor is discharged and switch A is closed. Switch B remains closed. What is the magnitude of the current I1through resistor R1 immediately after switch A is closed ? Thank you! After a very long time, the capacitor is discharged and switch A is closed. Switch B remains closed.
