... In this case, we will apply another law, Kirchhoff’s voltage law. This law says that is you sum all of the voltages around a closed loop, they will add up to zero. To apply this rule, pick any spot in a close loop, For example, let’s pick the lower left hand corner. As we go around the loop, if we e ...

... RDS(on) of 0.090Ω maximum at room temperature (and 26A). At 125°C the RDS(on) is double, so 0.180Ω per part. The maximum total resistance allowed is 1V / 20A = 0.050Ω. The minimum number of parts required to meet the on-state voltage requirement is found as: 0.180Ω / 0.050Ω = 3.6, so 4 parts minimum ...

Multimeter
.JPG?width=300)
A multimeter or a multitester, also known as a VOM (Volt-Ohm meter or Volt-Ohm-milliammeter ), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance. Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured. Digital multimeters are now far more common but analog multimeters are still preferable in some cases, for example when monitoring a rapidly varying value. A multimeter can be a hand-held device useful for basic fault finding and field service work, or a bench instrument which can measure to a very high degree of accuracy. They can be used to troubleshoot electrical problems in a wide array of industrial and household devices such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems.Multimeters are available in a wide range of features and prices. Cheap multimeters can cost less than US$10, while laboratory-grade models with certified calibration can cost more than US$5,000.
