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....
Where V is the voltage across the resistor, I is the current through the resistor and R is the resistance of the resistor, all in their respective units. The trick here is to use a resistor value that does not affect the overall circuit being measured, since the voltage drop across the ...
The current divider formula is applicable in situations where there is a parallel network of various elements. Also, the current divider rule formula can help you determine the current in every branch of a circuit. The main use of the current divider is to help generate a proportion of the a...
A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of theelectric currentthrough the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving it ...
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 mention...
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)/...
Ability to determine direct current or alternating current Introducing additional resistors into the tested circuit path may increase the source output resistance and result in adverse load effects. Due to the direction of power consumption, power will be lost. Therefore, current detection resistors are...
Objectives Describe how current divides in a parallel circuit. Determine the voltage across and current through each branch of a parallel circuit. Explain why circuit breakers and fuses are used in homes. Parallel Circuits A circuit with more than one path for the current to...
Linear oscillators: A harmonic oscillator produces a sinusoidal output. It relies on the principle of resonance, where an LC (inductor-capacitor) or RC (resistor-capacitor) circuit is used to determine the frequency of oscillation. The most common types include the Colpitts, Hartley, and RC Phase...
For example, if your voltage source is a 14 volt battery and the component you're driving is a motor with a resistance of 20 ohms, then the current will be 14 / 20, which equals 0.7 amps. Step 2 Add another resistor to the circuit (in addition to the resistance of the component you...
