How do you calculate Vo in a circuit?
To find the voltage at Vo, start at either end and add or subtract the voltage drop across the resistor.
- If we start at the 10V end: Vo = 10 – 3.58 = 6.42 V.
- If we start at the -2V end: Vo = -2 + 8.42 = 6.42 V.
What is v0 in voltage?
The dc voltage at an output terminal with reference to a common terminal, normally ground, when no signal is applied to the input.
How do you calculate source voltage?
Ohms law tells us that when a current, (i) flows through a resistance, a voltage drop is produce across the same resistance. The value of this voltage drop is given as i*RS. Then VOUT will equal the ideal voltage source, VS minus the i*RS voltage drop across the resistor.
How would one analyze a circuit with two voltage sources?
My intuition leads me to believe that the two voltage sources are acting against one another versus stacking their effect. When I search this problem online, I come across examples of superposition, which breaks the circuit apart, analyzes the individual parts, then brings the parts together in an additive or subtractive manner.
How to find the output voltage VO2 in circuit C?
In Circuit C, finding the output voltage vo2 due to vs2 also requires a voltage divider equation, with the polarities of vo2 opposite vs2. Using the voltage divider method produces the output voltage vo2 as follows:
What is output voltage due to VS1 and VS2?
The output voltage due to vs1 is vo1. Similarly, Circuit C is Circuit A with the other voltage source turned off. Circuit C contains one voltage source, with vs1 replaced by a short circuit. The output voltage due to voltage source vs2 is vo2. Summing up the two outputs due to each voltage source, you wind up with the following output voltage:
How to calculate Vout for a resistor R2?
The required output voltage (Vout) can be obtained across the resistor R2. Using these two resistors we can convert an input voltage to any required output voltage, this output voltage is decided by the value of the resistance R1 and R2. The formulae to calculate Vout is shown below. Vout= (Vin x R2) / (R1 + R2)
Now that we know the diode is conducting, apply a simple nodal equation at point of output, Solve for Vo, which will be approx 6.42V. Since you have more than one source of voltage in the circuit, why not use the Superposition Theorem ( http://en.wikipedia.org/wiki/Superposition_theorem ).
How to calculate the Vo of a resistor?
To find the voltage at Vo, start at either end and add or subtract the voltage drop across the resistor. You don’t “ignore” the other source(s) to use superposition, you connect them to ground. So the the voltage from the 10V source is 10V * (4.7/(4.7+2)), and the voltage from the -2V source is -2 * (2/(4.7+2)).
How to calculate Vo in a 4k7 circuit?
The voltage across the 4k7 is 1.791mA * 4k7 = 8.418 volts. But the bottom of the 4k7 resistor is 2 volts lower hence the output voltage is 6.418 volts. Neither of your answers are correct. First task at hand is to identify whether the diode is forward or reverse biased.
How to calculate the voltage in a circuit?
You correctly calculated the current through the whole circuit: 10 − ( − 2) 2000 + 4700 = 1.791 m A The next step you could take would be to calculate the voltage drop across each resistor: Across the 2K resistor: 2000 * 0.001791 = 3.58 V Across the 4.7K resistor: 4700 * 0.001791 = 8.42 V
