For simplicity, assume that the resistance of the light bulb is constant and equals the resistance the bulb must have to dissipate Determine electromagmetica for the given design considerations.

Does this result confirm the indjcao description of what is observed in the demonstration? The height of the liquid in the tank is d.

Switch S is closed at time causing a current through the inductive branch and a current electromxgnetica the capacitive branch. Obtain expressions for these steady-state currents. One coil has self-inductance and the other coil has self- inductance The mutual inductance of the two coils is M. The circuit elements are inudcao follows: Also, show that they satisfy the initial conditions where and d Deter- mine the time at which first becomes zero.

You can ignore any fringing effects and assume that the relative permeability of the material of which the tank is made can be ignored.

The four sides of the tank each have width W and height D Fig. 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. 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.

CP In the circuit shown in Fig. After a period induczo 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 Find the maximum charge that each capacitor will receive, and how much time after eleftromagnetica switch is flipped it will take them to acquire this charge.

When switch S is opened, a transient current is to be set up that starts at 0. A common demonstration of inductance employs a circuit such as the one shown in Fig.

Switch S is closed, and the light bulb repre- sented by resistance just barely glows. Two coils are wrapped around each other as shown in Fig. CP A Volume Gauge.

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. 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. A tank containing a liquid has turns of wire wrapped around it, causing it to act like an inductor.

Take The magnetic susceptibility of liquid oxygen is c Repeat part b for mercury. The liquid content of the tank can be measured by using its inductance to determine the height of the liq- uid in the tank. Enviado por Wallace electromagnetjca Denunciar.
