Resistance is a fundamental electrical property that measures how strongly a material opposes the flow of electric current. It is analogous to friction for water flowing through a pipe; just as friction slows the water down, resistance hampers the movement of electrical charge. Resistance is measured...
Using Ohm's law (Equation 1), you can determine the current consumption: V = IR (Equation 1) where V is the voltage, I is the current and R is the resistance.Choose the shunt resistor and op amp so that they will have minimal impact on the circuit's behavior. In selecting a ...
Step 1: Determine the known values for the current and the resistance. We are given that the resistance is 5.0 ohms, and the current is 2.0 amps. Step 2: Use Ohm's Law and the Power Equations to determine an equation to solve for the power with the given ...
Resistance, reactance, and impedance The three main components of an AC circuit are resistors, capacitors, and inductors. You can use this power factor calculator not only to describe the power that is transferred through each of these components but also to establish what happens when an electric...
(The equation for converting VAC in RMS to peak to peak voltage is to multiple by twice the square root of two.) They are rated to sustain surge voltages up to 800 VDC in transient mode. They all have very low on-state resistance, on the order of 33 mill...

DCR sensing is the method that senses current through a buck regulator’s output inductor. An inductor can be modeled as an ideal inductance and a series resistance called DCR (see Figure 6). This is typically the preferred method for high current (>20 A) rails. The addition of ...
One important property of depletion mode devices is that the drain-to-source resistance is close to 0 Ω when the gate voltage is equal to 0 V. As a result, to operate the device, a negative voltage must be applied to the gate. In Figure 1, this voltage is applied through an on-chi...
Before we get onto the op-amps we need to cover one more aspect of the circuit and that is those 10 resistors next to each other R1 - R10. They are 10 x 1 ohm resistors in parallel, parallel resistance can be a little confusing to calculate the total resistance of that section, howev...
