  • @uwezimmermann5427
    @uwezimmermann5427 5 ปีที่แล้ว +8

    good explanation, but you should mention that the big advantage of the wheatstone bridge is that the voltmeter actually shows the small deviation from the equilibrium and thus you can use a much more sensitive measurement range. In your example of 20 ohm resistors (quite low value by the way) if you would only measure one resistor which changes from e.g. 20 ohm to 20.2 ohm than this would only be a change of 1% seen on the last decimal on a regular multimeter. Even if you just measure the voltage on the right side, you end up with an unuseable value of just 5.02 V, also here the important information is hidden in the last digit of the multimeter. However, if you measure the difference between the two voltages, you get a value of 25 mV which you even might be able to read with an addition decimal in the millivolt range of your multimeter.

  • @RS_83
    @RS_83 5 ปีที่แล้ว +24

    There's a mistake on 4:43. The strain gauge resistance must be 20 ohm, just like R3, for a bridge to be balanced.
    Also on 5:30, the more temperature you apply, the more resistance increases. So, for example, it must increase to 22 ohms. But you're showing that it decreases. Otherwise very good, clear explanation! Thank you, dude!

      Temperature up resistance down

    • @clobraico_private9121
      @clobraico_private9121 4 ปีที่แล้ว

      disagree. Seems like an important reason for why this configuration is used is to account for resistors and systems not being ideal.. Although 20 ohms may make the bridge balanced in ideal conditions, this is real life. 23 ohms might be needed to balance the circuit due to the resistors not being ideal and environmental factors such as temperature

    • @gustavofoss2280
      @gustavofoss2280 4 ปีที่แล้ว +4

      @@clobraico_private9121 that would have been plausible if he had explained that pragmatic scenario. The explanation should stick to the theory. If you dont understand the theory you wont understand its real world effects and variations.

    • @MrAranton
      @MrAranton 2 ปีที่แล้ว

      Resistors come in large variation of properties and not all respond the same way to changes in temperature. Look up thermistors; they come with negative (i.e. temp goes up resistance goes down) and positive (vice versa) temperature coefficients.
      Now: Even resistors that aren't purpose built to respond to temperature coefficient. And whether the temperature coefficient of any given resitor is positive or negative depends on its construction and the materials its made from. Therefore the generalization "the more temperature you apply, the more resistance increases" is incorrect.

    Nice explanation, but using quarter wheatstone bridge as u showed in this video doesn't solve the problem with temperature messing up the measurement, because it's very likely that resistors used in this bridge will have different temperature coefficient than the strain gauge. We should use the half bridge instead, so 2 strain gauges , to make sure that the changing temperature won't mess up our mesurements, am
    I right?

    • @richardlighthouse5328
      @richardlighthouse5328 2 ปีที่แล้ว

      So R3 should also be a strain gauge? You will have a problem with 2 strain gauges measuring different forces.
