The current through a 58 mH inductor is measured 1.6 amps. How much energy is stored in millijoules? Question 15 10 pt One 3 mH and one 8 mH inductor are connected in series. What is the equivalent inductance (in mH)?
(a) How much energy is stored in a 10.2 mH inductor carrying a 1.15 A current? (b) How much current would such an inductor have to carry to store 1.0 J of energy? (c) Is this a reasonable amount of current for ordinary laboratory circuit elements?
Imagine that we connect a 10-mH coil to a battery through a resistor, and it settles down to conducting 1.0A. How much energy is now stored in its magnetic field?
2 parts, thx:)
1) Current of 4.0 A flows in the coil as shown in the figure.
The coil has 4 loops and is situated in the xz-plane. The area of
the coil is 3.00 x 10-3 m2. The coil is
situated in a uniform magnetic field = (2.00- 5.00- 5.00mT. What is the magnitude of the
torque acting on the loop due to the magnetic field? Give your
answer in µNm (micro-Newton meters).
2) Current of 2.0 A flows...
