WebThe first two digits indicate the resistance value—while the third digit is the multiplier. Resistor color code for 330 Ohms. For example: “482” = 48 x 100 ohms = 4.8 kiloΩ. If the resistors have values less than 100Ω, you can write it as: “480” = 48 x 10 0 (which is equivalent to 1) = 48 x 1Ω = 48Ω or 48RΩ. WebTo calculate internal resistance, we use a potentiometer to first calculate the voltage across the battery, with no current through it. Then we attach a resistor in parallel to the battery and recalculate the voltage across it. Since the current flows, this time the balancing length is smaller. Using the battery equation, we calculate the ...
WebMar 12, 2024 · This technique is often used in both analog and RF circuit analysis. Generalizing the network in question as a resistance R, we can calculate the value of R by dividing the voltage across R by the current through it: R = V / I. simulate this circuit – Schematic created using CircuitLab.
