AI Thread Summary
In America, standard outlets are type A and B, which operate at 120 VAC, while type E and F outlets are designed for 250 VAC. To use a device with a type E or F plug in the U.S., a step-up transformer is necessary to convert the voltage. The recommended product for this purpose is a step-up transformer, which can be found on Amazon. It's important to choose a transformer that matches the power requirements of the appliance being used. Devices designed for 250 volts will not function properly on 120 volts without the appropriate transformer.

I'm in America. Outlets don't look like this. Can't tell if the above outlet which I have is type E or F and not sure if America has type A or B. What product do I buy on amazon to deal with this?

In the US we use type A & B but our line voltage is 120 VAC where as your type E & F are for 250 VAC. Fairly sure you 250 volt stuff won't work on 120 volts.
 
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...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
