WebMar 6, 2024 · Some resistors have contact plates on the bottom. [5] 2. Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms. [6] WebMay 6, 2024 · R = 325 ohms. The closest standard value to that is 330 ohms. Now lets figure out the power rating required for the resistor: P = V * I (power = voltage times current) We are using 330 ohms instead of 325, so let's see exactly what the current will be: I = V / R. I = 6.5 / 330. I = 0.0197 amperes (19.7 milliamps). WebThe formula for power rating within watts is P = V*I. P = 10 x 0.04 = 400mW or 0.4 Watts. Example-2: When the current flows throughout a 1.8KΩ resistor which is rated at 0.5 Watts then calculate the maximum safe current flowing through the resistor. We know the values of R = 1.8 KΩ and P = 0.5 Watts. david blumenthal md cardiology
