If you do not know the resistance in one component of your circuit, look for ways to calculate it. If you know the voltage V and current I across that component, find its resistance using Ohm's Law: R = V / I. Method 4 Formulas Using Power 1 Learn the formula for power.

WebApr 28, 2024 · 1 You solve it via the following quadratic:RTOTAL = 1 1 R1 + 1 R = 4Ω + 1 1 R1 + 1 R1 = 3 4Ω = RR1 R + R1 + R1 2 = R2 1 + 3RR1 2(R + R1) ∴ 0 = R2 1 + (3RRTOTAL − 2RTOTAL)R1 − 2RRTOTALYou know R = 4Ω and RTOTAL = 3 4 Ω. You should be able to solve this for R1. – jonk Apr 28, 2024 at 2:48 Add a comment 1 Answer Sorted by: 1 WebWheatstone bridge. The condition to be satisfied at the point of balance is given below. If R2/R1 = R X /R3, then V BD = 0 and current through V G = 0. To reach this condition, the adjustable resistor is varied. The direction …
WebTake these two resistors in parallel, and think about what the equivalent resistance would be. And we have seen that before. One over the equivalent resistance is going to be equal to one over 6.0 ohms plus one over 12.0 ohms. 1/6 is the same thing as two over 12. So 2/12 plus 1/12 is 3/12. WebIf we know the bridge is balanced, we can discover the value of R4 with the formula: R4 = R3 * R2 / R1 If we know the values for all four resistors as well as the supply voltage, then we can calculate the cross-bridge voltage through ascertaining the voltage for each potential divider and then subtracting one from the other, thus:
WebBridge circuits can be constructed to measure just about any device value desired, be it capacitance, inductance, resistance, or even “Q.”. As always in bridge measurement circuits, the unknown quantity is always “balanced” against a known standard, obtained from a high-quality, calibrated component that can be adjusted in value until ...
