c1. What is the magnitude of the induced emf at t = 0 s?
c2. What is the magnitude of the induced emf after a long time has passed?
d. After the current in the RL circuit has reached its final value (as in b2. above) the positions of the switches are reversed, with S1 open and S2.
How long does it take for the current to reach a tenth of its initial value?

- 1Write out generic mathematical expressions for current and potential difference in a series circuit. 2What is magnetic induction? the creation of a magnet by bringing a magnet close to another non-magnetic material branch of physics dealing with the interaction of electric and magnetic fields an area surrounding a magnet in which a magnetic force acts on a moving charge a piece of metal that has atoms aligned such that it attracts other pieces of metal 3A square boat of area = 2 m2 floats on the water with 1 m of boat submerged in the water. Estimate the buoyant force on the boat and the pressure at the bottom of the boat. The density of water is 997 kg/m3. Fb = 30,000 N and P = 20,000 Pa Fb = 10,000 N and P = 20,000 Pa Fb = 100 N and P = 200 Pa Fb = 20,000 N and P = 10,000 Pa professor can you answer these 3 questions please?arrow_forwardPart A) Determine the energy stored in the inductor L as a function of time for the LR circuit of the figure.Express your answer in terms of the variables L, t, R, V0, and appropriate constants. U=? Part B) After how many time constants does the stored energy reach 99.9%% of its maximum value? Express your answer using two significant figures.arrow_forwardQ11. Please look at the circuit diagram given, the switch is originally kept at point a for a long time, then the switch is quickly flipped to point b.it is your job to determine the following. a. the frequency of current oscillations in the LC circuit. b. the current amplitude of the oscillations which result. 30.0 V 15.0 5.80 μF ele 48.0 mHarrow_forward
- In the circuit shown in the figure below, let L = 3.10 H, R = 3.10 02, and E= 120 V. What is the self-induced emf 0.200 s after the switch is closed? V + Need Help? S R www Read It Watch Itarrow_forwardI'm working on some homework and am stumped with this problem. Help would be great, thanks!arrow_forwardYour RL circuit has a characteristic time constant of 21.5 ns, and a resistance of 5.40 MΩ. A. What is the inductance (in H) of the circuit? B. What resistance (in MΩ) should you use (instead of the 5.40 MΩ resistor) to obtain a 1.00 ns time constant, perhaps needed for quick response in an oscilloscope?arrow_forward
