There are many common questions about electrical engineering, but one often asked in academic settings is "How does the induced voltage react after a conductor traveling through a magnetic field speeds up?" Another common question is "What is the formula to calculate current when voltage and resistance are known?"
The question about the behavior of induced voltage following an increase in the speed at which a conductor travels through a magnetic field relates to the electrical engineering topics of magnetism and electromagnetism. The answer is that the voltage increases. Another common question relating to magnetism and electromagnetism is "What happens to the flux density of a wireround core after the current through the coil increases?" The answer is that the flux density increases.
Ohm's Law is another topic covered in a standard electrical engineering curriculum. The law is summarized by the formula V = I x R. In this formula, V stands for the voltage, I represents the current, and R refers to resistance. Electrical engineering students can rearrange this equation as needed based on the known variables in a given situation. Thus, the answer to the question "What is the formula to calculate current when voltage and resistance are known?" is "I = V / R." This is arrived at by dividing both sides of the equation by R to isolate the unknown variable.
