CETa Study Guide Questions and Answers Rated A+ What is voltage, and why is it important in an electrical circuit? Voltage is the measure of electrical potential difference between two points. It is essential because it drives the flow of current through a circuit. What does frequency indicate in an AC circuit? Frequency indicates how often the current changes direction in an AC circuit, typically measured in hertz (Hz), which impacts how electrical devices operate. How does en...

when electrons are forced to move thru a conductor the magnetic fields of individual electrons subtract from one another T or F - ACCURATE ANSWERS False the direction of the electromagnetic field around a conductor because of current flow is determined by the right hand rule as it relates to the electron theory T or F - ACCURATE ANSWERS false the field intensity around the conductor carrying current increased current flow and is stronger the further the distance from the conductor ...
