A changing magnetic field pierces the interior of a circuit containing three identical resistors. Two voltmeters are connected as shown. V1 reads 1 mV across R. V2 reads the voltage across the other two resistors, which is: 1mV
What the explanation for the above answer?
Although both voltmeters are connected to the same endpoints, if the system incorporates fluctuating magnetic fields, it is no longer correct that they must show the same voltage.
The changing magnetic field induced by the mobility of the material produces a current in the wire coil proportionate to the field fluctuation.
What are resistors used for?
Resistors are utilized in a heater, toaster, microwave, electric stove, and a variety of other heating appliances due to their ability to generate heat when carrying electricity.
The metal filament of a light bulb shines white-hot due to the extremely high temperature created by the resistance when electricity is conducted through it.
