AI Thread Summary

Transformers induce voltage in the secondary coil through electromagnetic induction, where a changing magnetic field around the core generates an electric current. This process relies on Faraday's Law, which states that the induced voltage is proportional to the rate of change of the magnetic flux. The interaction between the primary coil's alternating current and the core creates a magnetic field that "moves" and influences the secondary coil. Understanding the specifics of this phenomenon requires a grasp of the underlying mathematics and physics principles. For further details, resources like HyperPhysics can provide in-depth explanations.

Hi

How do transformers get voltage in the secondary? I am after the boring details of the "magnetism" moving and dancing in/at/around/on the core to induce that voltage?

thx

Hi samjesse,

Without know your math level of education it's hard to give you a good answer, but here a link that you can checkout: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html#c1"

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
