CP A Volume Gauge. The height of the liquid in the tank is d. The liquid content of the tank can be measured by using its inductance to determine the height of the liq- uid in the tank. Determine and for the given design considerations. When switch S is opened, a transient current is to electromahnetica set up that starts at 0.

Does this result confirm the qualitative description of what is observed in the demonstration? The magnetic susceptibility of mercury is given in Table Take The magnetic susceptibility of liquid oxygen is c Repeat part b for mercury.

Also, show that they satisfy the initial conditions where and d Deter- mine the time at which first becomes zero. You are to connect a resistor in series with the inductor, and represents the sum of that resistance plus elecctromagnetica internal resistance of the inductor.

The current travels in the electrlmagnetica sense around each coil. The inductance of the tank changes from a value of corresponding to a relative permeability of 1 when the tank is empty to a value of corre- sponding to a relative permeabil- ity of the relative permeability of the electromagnrtica when the tank is full.

The circuit elements are as follows: You can ignore any fringing effects and assume that the relative permeability of the material of which the tank is made can be ignored. Find the maximum charge that each capacitor will receive, and how much time after the switch is flipped it will take them to acquire this charge.

The four sides of the tank each have width W and height D Fig. Obtain an expression for the electromagneticq through the inductor and light bulb as an explicit function of time. For simplicity, assume that the resistance of the light bulb is constant and equals the resistance the bulb must have to dissipate Enviado por Wallace flag Denunciar.

Two coils are wrapped around each other as shown in Fig. Obtain expressions for these steady-state currents. A common elecrromagnetica of inductance employs a circuit such as the one shown in Fig.

CP In the circuit shown in Fig. One coil electromatnetica self-inductance and the other coil has self- inductance The mutual inductance of the two coils is M.

A tank containing a liquid has turns of wire wrapped around it, causing it to act like an inductor. After a period of time, switch S electromagneetica opened, and the bulb lights up brightly for a short period of time.

Switch S is closed at time causing a current through the inductive branch and a current through the capacitive branch. Switch S is closed, and the light bulb repre- sented by resistance just barely glows.

The appropriate electronic circuitry can determine the induc- tance to five significant figures and thus the effective relative per- meability of the combined air and liquid within the rectangular cavity of the tank.
