A 200-Loop Coil of Cross Sectional Area 8

question 11

Short Answer

A 200-loop coil of cross sectional area 8.5 cm² lies in the plane of the page.An external magnetic field of 0.060 T is directed out of the plane of the page.The external field decreases to 0.020 T in 12 milliseconds.
(a)What is the magnitude of the change in the external magnetic flux enclosed by the coil?
(b)What is the magnitude of the average voltage induced in the coil as the external flux is changing?
(c)If the coil has a resistance of 4.0 ohms,what is the magnitude of the average current in the coil?

Voltage Dividers

Circuits that reduce voltage to a lower value, using a series connection of resistors or other components to distribute the input voltage into smaller outputs.

Field-Effect Transistors

Semiconductor devices used to control the electrical behavior in circuits, relying on an electric field to control the flow of current.

Multirange Voltmeter

An instrument designed to measure voltage levels in multiple ranges, allowing for flexibility and accuracy across different electrical applications.

Wire-Wound

Describes a type of resistor or inductor made by winding a wire, usually made of a resistive material, around a core.
