Now we can have two possible … WebPotentiometers come in different forms but they are generally classified basing on their Resistance (R-ohms) and Power (P-Watts) ratings. The value or resistance decides how much opposition it provides to the flow of current. The greater the resistor value the smaller the current will flow.
WebFeb 24, 2012 · It uses one ammeter to measure current, I and one voltmeter to measure voltage, V and we get the value of resistance as. Now we can have two possible connections of ammeter and voltmeter, shown in the figure below. Now in figure 1, the voltmeter measures voltage drop across ammeter and the unknown resistance, hence. WebAug 9, 2016 · You can't measure resistance directly. What you can do however is measure the voltage across a potentiometer. There is a really good example provided by arduino …
WebJul 5, 2024 · Case 1 – When voltmeter is directly connected across the resistor, then the ammeter measures current flowing through the unknown resistance (R x) and the voltmeter. Current through ammeter = Current through (𝑅 x) + Current through voltmeter I = I R x + I V ⇒ I R x = I − I V Therefore, the value of unknown resistance,
