The capacitor voltage is measured with two leads across the capacitor and is connected to the AI 1+ and AI 1- screw terminals. The resistor voltage is measured with two leads across the resistor and is connected to the AI 0+ and AI 0- screw terminals. From your NI ELVISmx Instrument Launcher strip, select [FGEN].
Resistors are used to reduce current flow, divide voltages, terminate transmission lines and adjust the signal levels. Capacitors are used for filtering, smoothening, coupling different sections of the circuit and limiting high voltage transient across the circuit. Resistors create power loss and generate heat.
A 0.1 μF capacitor is connected in series with the resistor. The other end of the capacitor goes to the AGND screw terminal. The capacitor voltage is measured with two leads across the capacitor and is connected to the AI 1+ and AI 1- screw terminals.
Resistors are the most common components used to introduce resistance into a circuit. They are passive components that dissipate electrical energy in the form of heat when current flows through them. One of the primary attributes of resistance is its ability to control the flow of current.
The power dissipated by the resistor is equal to the voltage multiplied by the current: If I is measured in amps and V in volts, then the power P is in watts. By plugging in different forms of V=IR, we can rewrite P=IV as: or The symbol for a capacitor: or The capacitor on the right is polarized.
In an electrolytic capacitor, the gap between the two plates is filled with dielectric medium of higher permittivity so that the capacitance is increased. Other units also used for capacitance include , , and . The amplitude of the current is proportional to the frequency of the voltage.
Capacitor vs. Resistor: What''s the Difference?
Resistors are typically measured in ohms, while capacitors are measured in farads. For example, a resistor rated at 1kΩ is 1 kilo-ohm or 1000 ohms. A capacitor rated at 10µF (microfarad) is 10 millionths of a farad.

What Is the Difference Between a Resistor and a Capacitor?
In contrast to resistors, capacitors are electrical components designed to store energy in an electric field. A capacitor consists of two conductive plates separated by an insulating material called a dielectric.

Capacitive Voltage Divider Circuit as an AC Voltage Divider
Consider the two capacitors, C1 and C2 connected in series across an alternating supply of 10 volts.
