Area Copper Power

AI Thread Summary

To determine the appropriate area of copper for a terminal based on power requirements, it's essential to know the motor's voltage and current ratings. The discussion emphasizes the need for the correct formula to calculate the cross-sectional area of copper wire, which is crucial for ensuring safety and efficiency. Participants suggest that the area can be derived from the power formula, taking into account factors like current, voltage, and allowable temperature rise. Additionally, they recommend consulting electrical engineering resources or standards for precise calculations. Accurate sizing of the copper terminal is vital for optimal motor performance and safety.

Hi,

Im not an electrical engineer, not even close to one, but I have been asked to design a terminal for a motor. I have the power (current and voltage) requirements so I need to work out what area of copper in the terminal will handle this power.

Can anyone give me the equation, or point me in the right direction to get this figure?

Regards,

James

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...
