really nothing more than a highly accurate resistor. When we place a precision resistor across a circuit, a voltage drop will occur across it. The shunt sensor’s output is measured by the data acquisition system, which applies Ohm’s law to determine the amperage flowing through the circuit....
In the image above with the splice in the cable, the module will measure the current flowing to all devices plugged into the power strip. Figure 4: For module measurement using a CT, the load wire (black in the US), is passed through the opening of the CT either via a split core ...
In order to understand the calculation of equivalent resistance in series, consider N-resistor namely R1, R2, R3,…RNconnected in series as shown in Figure-1. Let, the total voltage across the combination is V volts, and I is the total current through the combination. It should note that ...
(V) across a resistor (R) in terms of the work done in moving a unit charge. State the relation between these two works and the work it charge through a cell connected across the resistor. Take the internal resistance of the cell as r. Hence, obtain expression for the current i in ...
In a parallel connection, the potential difference across each resistor is the same. The current through each resistor, however, is different and is inversely proportional to its resistance. Answer and Explanation:1 R1 R2 Learn more about this topic: ...
Thus, we get voltage equals the power divided by current. Mathematically, Example 2 As shown in the below circuit a current of 2 A is flowing through a lamp of 48 W. Determine the supply voltage. Solution: Given Data: , According to the formula between voltage, power, and current menti...
1. Using a Shunt Resistor This is perhaps the simplest way to measure current, and will be discussed here in detail. The current-to-voltage converter here is the humble resistor. Basic knowledge tells us that the voltage across a resistor is proportional to the current flowing through it. Th...

Using Ohm’s Law: To determine the current flowing through a shunt resistor, Ohm’s law is applied by measuring the voltage across the resistor. Construction Tips: When building a shunt resistor, the type of wire and its length are crucial to achieving the desired resistance and functionality....
This is the formula we can use for choosing the resistor value we need to get any voltage we want. So back to our circuit, if we have 5 volts and want 3V from it, we use the formula above. If we use a 10KΩ as our R1resistor, plugging in the values, we get R2= (V)(R1)/...
