ohms law - How is open-circuit voltage calculated? - Electrical ...
2016年10月22日 · It also could be just as well said that it "a difference in voltage potential must be present across it." It doesn't matter whether you think of it as the current creating the voltage, or the voltage creating the current, so long as you know that Ohm's Law tells you that there will be such a voltage if there is such a current, and visa versa. Okay.

2017年9月3日 · Simply apply the principle of superposition: replace your current source with an open circuit, and calculate the voltage across the 800Ohm resistor. Then, replace your voltage source with a short circuit, and again calculate the voltage across the 800Ohm resistor, remembering that currents at a node will always sum to zero (Kirchoff's Current Law).

2016年1月19日 · Also, All of the current from the 8 A current source is going through the 5 ohm resistor. the voltage across the 5 ohm resistor is \$40 \$ Volts. You already pointed out that the voltage across the 13 ohm and the 9 ohm resistor is zero. The voltage across the 18 ohm resistor is 15 volts by definition. The voltage at point a with respect to ...
Kirchhoff's laws in an open circuit
It asks to find the voltage across the points a and b. I first redesigned the circuit to make it look for straightforward and I figured that no current goes through 1000 Ohm resistor since point a is not attached to anything, thus, the potential difference there should be zero. Also, according to KVL, voltage within a loop should be zero, thus ...
How to find Thevenin equivalent resistance with dependent …
2021年9月27日 · Short circuit any independent voltage source, open circuit any independent current source (leave dependent sources alone). Apply a 1 A current source at the port where you are determining the Thevenin equivalent and compute the voltage across that current source. That voltage, expressed in ohms, is the Thevenin resistance.

2020年12月19日 · Now, looking the right side of the circuit, from A down to (-) terminal, you can note a parallel of 6//(4+2) = 3 ohms. At this point, considering the left side too, we will have a very simple circuit with 9 V and two 3 ohms series resistance; therefore, the voltage on point A is 9/2 V. Knowing the voltage at node A , it's easy to calculate the ...
