How do you calculate R2 in a circuit?
The resistance of each element is given by the formula Rj = V / Ij. For example, if you have three resistors in parallel with a voltage drop of 9 Volts and currents I1 = 3 Amps, I2 = 6 Amps and I3 = 2 Amps, the resistances are R1 = 3 Ohms, R2 = 1.5 Ohms and R3 = 4.5 Ohms. 1 / Req = 1 / R1 + 1 / R2 + …. 1 / Rn.
What is the current in R2?
Since R2 looks (to source V2) as though it is grounded, the current through R2 is V2/R2; similarly, the current through R3 is −V3/R3. In the same way as for current sources, the voltage drop in RF, and hence the output voltage, is equal to −(Iin + V2/R2 − V3/R3)RF. Figure 30-11.
How do you calculate Vo in a circuit?
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 does the VO2 max calculator work for You?
Put in the data into the calculator, and also fill in your age, weight and select your sex. Three minutes step test. The test bases on stepping up 16.25 inches (0.41 m) from ground level. You will also need a stopwatch and a metronome. As previously, do some basic stretching and warm up before the test.
