Explain, with the aid of a circuit diagram, how ad.c. voltmeter may be calibrated by means of a potentiometer method.A moving-coil instrument, used as a voltmeter, hasa coil of 150 turns with a width of 3 cm and an activelength of 3 cm. The gap flux density is 0.15 T. If thefull-scale reading is 150 V and the total resistance ofthe instrument is 100 000 Ω, find the torque exertedby the control springs at full scale.

Electrie Battery is a device that stores chemical energy andtransforms it to electrical energy16. Resistors are electrical components that helps the Now ofelectrical current in an electronic circuit.17, Electron current flow is a current flow from the positive terminalto the positive.18, Gauss' s Law states that the total electric Nux out of a closedsurface is equal to the charge enclosed divided by Eo.19. Electric Potential Energy is the energy that is needed to move acharge against an electric field.20. 8 is called the permittivity of free space.

Answer each of the following conceptual questions in one or a few complete sentences. It's sufficient to explain the 'main idea' and not all of the small details. (a) Why do circuit elements in series have the same current? (b) Why do circuit elements in parallel have the same voltage/potential difference? (c) forces, and sometimes from electric forces. How can you decide which one exerts the force in a given situation? The induced emf E calculated from the flux rule sometimes comes from magnetic (d) currents are anywhere nearby to create the fields. Briefly explain how electromagnetic waves can exist even when no net charges or

Electrical Engineering One great effect of the dialectic or contestation over technology is the innovation that results. Is there a service or product that you use that might have resulted in opposition to the way that things had been done? (MIT question)

a) One early customer concern about electric cars was the chemical longevity of the battery. An alternative would be to store energy in a "super" capacitor (a large capacitor). i) A small electric car stores 5.7x107J in a fully charged battery. What volume would a vacuum-filled capacitor have to have in order to store this much energy? Assume that safety regulations limit the electric field in air to 0.8x10° V/m ii) How could we effectively increase the capacitance without changing either the area or plate separation? b) Consider the following circuit: A V,=3 V +V3=4 V V2=5 V - /2 13 R3=1 kN R-600 Ω Σ R,=800 N i) Use Kirchhoff's current rule to find an equation relating the currents at Junction A. ii) Write an equation applying Kirchoff's voltage rule to the right loop. Given that I, = 1.17 mA, determine the current l2. iii)

On one of my many trips to Menards, I purchased a 14 watt LED “soft white" light bulb with an output of 1600 lumens and provides light output equivalent to a 100 watt incandescent light bulb. The A19 form factor bulb is designed to operate on a standard 120 V, (a) The "soft white" output corresponds to a black body radiator with a thermal temperature equivalent to approximately (1000K, 2700-3000K, 5000K to 5500K) while the "bright white" fluorescent lighting in a classroom corresponds to a black body radiator with a thermal temperature equivalent to approximately (1000K, 2700-3000K, 4500K to 5500K). 60 Hz power line. rms
