WebOct 11, 2016 · You can algebraically manipulate i=v/r into different forms. v=ir and r=v/i are all equally true. Ohm's law (the name for that formula) is extremely useful and versatile. You can use it to find the relative voltage of every point and the current through every wire in simple diagrams. WebSep 22, 2015 · First, you have to follow ohm's law to find the total resistance. 120/9.6 = 12.5 Ω. (this is your Rt) next, this gets a little more complicated, the Rt = the reciprocal (1/) of the sum of reciprocal of the individual resistors (1/R1 + 1/R2 + 1/R3.) The easiest way to break this down is to to lay it out algebraically, so lets do it! 12.5 = 1/
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: 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
