Capacitive touchscreens are more expensive to manufacture than resistive touchscreens. Different types of stylus are used for resistive and capacitive touchscreens. Touchpads operate in one of several ways, including capacitive sensing and resistive touchscreen. Edges of the resistive layer have conductive contacts. The feedline sees a purely resistive impedance. It is an example of a thermal circuit with one resistive and one capacitative element. CMOS circuitry dissipates less power than logic families with resistive loads. It can also be used as dielectric in resistive random access memories. Level shifts caused by resistive heating of the voice coil are termed power compression. Superconducting magnets have a number of advantages over resistive electromagnets. This is a result of higher carrier mobilities and lower resistive device parasitics. Source transformations are not limited to resistive circuits. This device essentially consists of a glass tube with a resistive coating on the inside. This large eddy current flowing through the resistance of the pot results in resistive heating. The resistive element can be flat or angled.
