Question No. Update date. Magnitized material . Which of the following is true in this case? 34. The energy stored in a magnetic field is equal to the work needed to produce a current through the inductor. Static resistance R of a diode can be defined as the ratio of voltage V across the diode to The current flowing through the diode. Why then its effect is neglected in magnetism of materials? This video is unavailable. A-2. Check with your boat or small engine repair shop to see if the magnet can be recharged before replacing the magneto. A. A Trivia Quiz On Magnetic Particle Testing! Physics Lab Viva Questions. Questions & answers on resistors . Questions & answers on various topics >> Questions & answers on resistors. In general the Hall effect refers to the fact that a … The phenomenon, called magnetoresistance, is due to the fact that the drift velocity of all carriers is not same. 31. Writer Bio. 1. The device used to measure the voltage is provided with a very high input impedance (ASTM F84 recommends at least 10^6 x the resistivity of the specimen), thus the contact resistance is a small proportion of the resistance in the voltage measuring circuit. Electric motors and loudspeakers both use electromagnets. 2. A dotted line is drawn perpendicular to the magnetic meridian. If the magneto is generating the proper ohms, check to make sure the spark plug is working properly. Sample Question. A-4.
