WebJoules is a direct relationship, one Joule here equals one watt-second not watt-hour so to get your energy in joules you have to multiply your watt-hour in the figure by 3,600 because it’s 3,600 seconds in an hour. So if you do that and you look at a double a triple a and a double a better you triple a battery 1.4 watt-hours. WebBasic meters will usually have three ports to measure the following: 1. COM 2. Volts/Ohms 3. Amps Some DMMs have only one port for Amps, while some have milliamp ports and Amp (shown below). The milliamps port is used for measuring currents less than 300 mA (typical) for a more exact reading. Web25 mei 2006 · The voltage sensing is from the +Vin of the opamp. The input voltage is directly proportionate to the voltage across Rf developed by the current through the meter and Rf (since the opamp ideally draws no current from -Vin). This solution is also independent of the resistance of the meter. how do you make stuffed cabbage
