How transformer loss vary with load current?

AI Thread Summary
Transformer losses are influenced by load current, primarily through copper losses, which increase with the square of the current (I^2R losses). The discussion highlights the need to understand various loss mechanisms, including core losses and copper losses, which can vary depending on transformer type and operating conditions. Context is important for addressing transformer efficiency and performance, particularly in educational settings or practical applications. Different transformers may exhibit distinct loss characteristics based on their design and materials. Understanding these factors is crucial for optimizing transformer performance and minimizing energy loss.

Welcome to the PF.

What is the context of your question? Is it for schoolwork? What can you tell us about how transformers work, and what their loss mechanisms are? Are there different loss mechanisms for different kinds of transformers?
 
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...
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...
