PHYC 240-EXAM 3-Practice Problems 3) A 2.00 nF capacitor is charged with a 60.0 V battery. The battery is then removed The charged capacitor is then attached to a 2000.0 ohm resistor at t -o. a) What is the time constant? b) How long until the the charge drops to 20% of its original value? You have an extra 2000.0 ohm resistor. How would you add it to the circuit to reduce the time constant by one half? Draw the...
(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...
Circuit diagram included below. A) Do a thought experiment and replace resistor C with one that is 2x larger than the value of resistors A, B, and D. How will the current through the new resistor C compare to resistor B? How will the voltage drop across the new resistor C compared to resistor B? B) Now go back to thinking about identical resistors and continue this thought experiment by replacing all resistors with light bulbs (keep in mind that...
solve the following two elctromag problems Dirac in 1931. Dirac showed that if any magnetic monopoles exist in the universe, then all electric charge in the universe must be quantized (now known as the "Dirac quantization condition") electric charge is, in fact, quantized, which is consistent with (but does not prove) the existence of . (4 points) Write all four of Maxwell's equations if magnetic monopoles exist. . (6 points) If a monopole sits at the origin, its magnetic field...
The figure shows two unequal polat charges, and, of opposite siga. Charge has greater magnitude than charge. In which of the region X Y Z will there be a part which has electric field due to these two charge is wro? a) only regions X and 2 b) only region X c) only region Y d) only region Z e) all three regions 2. A light bulb is connected in the circuit shown in the figure with the switch Sopes....
The bulbs in the given circuit are identical and the battery is ideal. Part a onsider the circuit as shown. Figure 2 i. Rank bulbs A, B, and C in order of brightness. Explain how you determined your answer. ii. Rank the voltages across the bulbs. Explain. iii. Write an equation that relates the voltage across bulbs A and B to the battery voltage. iv. Is the voltage across bulb A greater than, less than, or equal to one half...
13.1 Charge Charge is quantized, quantum of charge e-1.6 x 10-19 C (coulombe). Any charge q- mentioned. ne,n-integer. Total charge in an isolated system. In these problemms, ignore gravitational attraction between objects unless explicitly L. Name a few things in your real-life experience that are quantized, ie. are an isteger maltiple of some smallest quantity 2. When you balance a chemical reaction, you make sure that what is/are the same on both sides of the chemical equation? Why? 3. You...
I need help with all these please! Thanks! 1. Two identical metal balls are suspended by insulating threads. Both balls have the same net charge. In this problem, do not assume the balls are point charges Ball 2 a. Draw a separate free-body diagram for each ball. Label the forces to indicate: . the object exerting the force, the object on which the force is exerted, • the type of force (gravitational, normal etc.), and • whether the force is...

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...
