Working Principles of the Current Sensing Resistors in Vietnam | Selectech
Current sensing resistors, also known as shunt resistors, play a vital role in electronic circuits by accurately measuring the flow of electrical current. These components are indispensable for various applications, from power supplies and battery management systems to motor control and industrial automation. Selectech, a leading supplier of current sensing resistors in Vietnam , offers a wide range of high-quality current sensing resistors tailored to meet diverse needs. How Current Sensing Resistors Work The principle behind current sensing resistors is based on Ohm's Law, which states that the voltage drop across a resistor is directly proportional to the current flowing through it. By placing a known resistance (shunt resistor) in series with the circuit, we can measure the voltage drop across it and calculate the current using the following formula: Current (I) = Voltage (V) / Resistance (R) The shunt resistor's resistance value is typically very low to minimize t...
