resistive touchscreens can only handle one touch point at a time.. whereas capacitive touchscreens can handle multiple touch points and are optimized for the human finger

What is the Difference between resistive and capacitive load?
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
What is Pure Resistive?
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.

In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
What is tft touchscreen means?
A resistive touchscreen panel is composed of several layers. The most important are two thin metallic electrically conductive and resistive layers separated by thin space. When some object touches this kind of touch panel, the layers are connected at a certain point; the panel then electrically acts similar to two voltage dividers with connected outputs. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing.
What is the difference between an ipod touch and an mp3 touchscreen?
they are different brands
How do you communicate between touch screen controller and a microcontroller?
If it is a resistive touch screen you can just use an ADC to interpret input (or an analog pin on your micro controller). Chips designed to interface directly with a touchscreen usually use SPI or UART or I2C to communicate, so just check the data-sheet on the controller, and you should be able to get it working. If it is a capacitive screen it will be harder, especially since, as far as I know most capacitive screens have a built in controller, and are usually difficult to work with. hope that helps
What is the difference between capacitive and resistant touch screens?
TFT (Thin Film Transistor) is a type of LCD display and is not related to touchscreen technology in any way; a better question would be, "What is the difference between resistive touchscreens and capacitive touchscreens?"Resistive screens are an older design, in which two electrically conductive layers are separated by an insulating gap. When pressure is applied, the resistance between the layers changes at that point. While cheap and reasonably durable, they require styluses, don't support multi-touch and can reduce the quality of the displayed image.Resistive screens were used in the original Palm Pilot and later Palm devices, in some portable games like the Nintendo DS, and in some current applications where their low price outweighs their limitations.Capacitive touchscreens use newer technology that also relies on electrical conduction, but senses changes in capacitance rather than resistance. Since human skin conducts electricity, moving a finger near the electrostatic field of a capacitive touchscreen will change the field, and the change can be measured and interpreted as a touch. Although they can be triggered by metallic objects, cloth, and other materials and are more expensive than resistive sensors, capacitive screens don't require syluses, support multi-touch, and can be made perfectly transparent.Capacitive screens are used in many new smartphones and tablets, including the iPhone, iPad, the Droid Incredible, Blackberry Storm, etc. The iPod trackwheel is an example of this technology used without a display.
What is the major difference between noncombustible construction and fire resistive construction?
Basically non combustible and fire resistive are the same. Difference is non combustible has steel frame members that are unprotected or limited protected. Fire resistive has protected steel frame members with a fire rated material such as concrete.
What is the difference between an inductive and a capacitive load?
Resistance load it means there is passive load to impede current flow. Inductive load means there is a coil as a load while still a passive it has its own characteristics which differs from a resistive load which is linear while inductive is not linear load
How does touch screen capacitive works?
touch screen capacitive works by the capacitance differential between the screen and your finger wherever there is difference in capacitance on the screen is where you are touching and the screen knows what function you are trying to do depending on what is displayed on the screen.
When is the power factor of a motor 1?
When the circuit is purely resistive or in resonance, i.e. capacitive and inductive reactance cancels out.Power factor is the ratio of apparent power over true power, and is the cosine of the phase angle between voltage and current.
