A common demonstration of inductance employs a circuit such as the one shown in Fig.

The circuit elements are as follows: Take The magnetic susceptibility of inucao oxygen is c Repeat part b for mercury. For simplicity, assume that the resistance of the light bulb is constant and equals the resistance the bulb must have to dissipate The height of the liquid in the tank is d.

Does this indcuao confirm the qualitative description of what is observed in the demonstration? The liquid content of the tank can be measured by using its inductance to determine the height of the liq- uid in the tank. Also, show that they satisfy the initial conditions where and d Deter- mine the time at which first becomes zero. When switch S is opened, electromqgnetica transient current is to be set up that starts at 0.

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 is opened, and the bulb lights up brightly for a short period of time. The magnetic susceptibility of mercury is given in Table You can ignore any fringing effects and assume that elecromagnetica relative permeability of the material of which the tank is made can be ignored.

Obtain an expression for the current through the inductor and light bulb as an explicit function of time.

The current travels in the same sense around each coil. You are to connect a resistor in series with the inductor, and represents the sum of that resistance plus the internal resistance of the inductor.

Two coils are wrapped around each other as shown in Fig. 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.

Enviado por Wallace flag Denunciar. Switch S is closed at time causing a current through the inductive branch and a current through the capacitive branch.

CP In the circuit shown in Fig. CP A Volume Gauge. The four sides flectromagnetica the tank each have width W and height D Fig. Obtain expressions for these steady-state currents.

Switch S is closed, and the light bulb repre- sented by resistance just barely glows.

One coil has self-inductance and the other coil has self- inductance The mutual inductance of the two coils is M. 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 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 liquid when the tank is full.

Determine and for the given design considerations.
