WebSep 12, 2024 · Here, we note the equivalent resistance as Req. Figure 10.3.5: (a) The original circuit of four resistors. (b) Step 1: The resistors R3 and R4 are in series and the equivalent resistance is R34 = 10Ω (c) Step 2: The reduced circuit shows resistors R2 and R34 are in parallel, with an equivalent resistance of R234 = 5Ω. WebDec 14, 2024 · The formula for calculating a total of n number of resistors wired in series is: R eq = R 1 + R 2 + .... R n That is, all the series resistor values are simply added. For example, consider finding the equivalent resistance in the image below [2] In this example, R 1 = 100 Ω and R 2 = 300Ω are wired in series. R eq = 100 Ω + 300 Ω = 400 Ω Method 2 WebThe video introduces the equation for the resistance in a wire using Ohm's law. system backup software for windows 10
