- Example Question 1 A dynamometer-type AC ammeter made of moving coils and fixed coils with a shunt is used to measure current. The ammeter is designed to let 95% of the input curent flow through the shunt resistor. The moving coil's resistance is 10 2, and the shunt resistance is 0.004 2. The Table Q1 below gives the relation between the deflection and the mutual inductance of the ammeter. Table Q1 Deflection 2.44 (radian) (full- scale) 0.26 0.52 1.05 1.57 1.83 2.09 Mutual Inductance -325 -260 -180 180 263 325 373 (µH) If the input current that gives the full-scale deflection is = 6.7A, determine the following: (i) (ii) (iii) the current passing through the moving coil at full-scale deflection, the deflecting torque that gives full-scale deflection, the current passing through the fixed coil at half-scale deflection. (Hint: Plot the Mutual Inductance vs. Deflection graph based on the table above. Then, use the graph to solve parts (ii) and (iii))arrow_forward3. You have seen how Kirchhoff's laws were used in your lectures to obtain a 2nd order differential equation where we solved for the current. This time we will use an even simpler concept: principle of conservation of energy to derive the 2nd order differential equation where we will solve for the charge. Take a look at the circuit below. IHE 2F In the circuit above, we have a capacitor with capacitance 2 F, an inductor of inductance 5 H and a resistor of 32 (a) The total energy that is supplied to the resistor is LI? E = 2 Q? 20 where L is the inductance, I is the current, C is the capacitance and Q is the charge. Write down the total energy supplied E in terms of Q and t only. OP Remember that I = dt (b) Now you know that the power dissipation through a resistor is -1R. Use the conservation of energy (energy gain rate = energy loss rate) to derive the differential equation in terms Q and t only.

- Suppose we have an 80-lb lead-acid battery. 10% of the weight of the battery is active material on the plates, i.e., we have a total of 8 lb of active Pb and PbO, on the plates that can be used to make electric power. Use the Gibbs free energy method to estimate the total stored energy in the battery. Assume that the open circuit voltage for a lead-acid cell is 2.1 V. [The answer should be a little less than 1 kilowatt-hour of energy.]arrow_forwardElectromagnetic Pulse propagating at oblique angle to a dielectric interface Consider a gaussian wave pulse propagating along the z-axis from region 1 with refractive index n1 and onto a dielectric interface y = m z (for all x). To the left of this dielectric interface, the refractive index is n2. Devise an initial value computer algorithm to determine the time evolution of the reflected and transmitted electromagnetic fields for this pulse. e.g., n1 = 1 , n2 = 2 initial profile (t = 0, with z0 < 0) Ex = E0 exp[-a (z-z0)^2] By = n1 * Ex Choose parameters so that the pulse width is at least a fact of 8 less than the z- domain of integration ( -L < z < L). For the slope of the interface, one could choose m = 1.arrow_forward6.

This relationship fails for large values of i. When the armature ratates, z generates a back electromotive force (back EMF) that opposes the applied valtage. In the circuit diagram, this is represented by a mator symbol. The voltage drop dua to the back EMF, denoted e, is proportional to the rotational velocity af the armature e-kp where k, is a constant of proportionality. Ta derive the relationship between the current i and the motor shaftt angular position 0. yau can apply KirchhofT's voltage law and Nowton's second law in terms of torques acting on the motor shaft. Kirchhoff's voltage law implies that the sum at the vatage drops across the circuit must equal tha applied voltage: iR + (1) where v is the…arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
