Neither 3 ohms nor 8 ohms is more powerful; the ohm is not a unit of power but of resistance to electrical current. However, an 8-ohm resistor has a greater ability to resist or reduce power.
Know MoreResistance to electrical current is often attained in electrical circuits with the use of a resistor. A resistor's ability to resist current is measured in ohms. Given a particular voltage, a higher amount of ohms means that there is a lower current flowing through the resistor. A decrease in current flow at a given voltage means a decrease in power. Therefore, a resistor with a higher ohm rating typically indicates a lower power output.
Learn more about MeasurementsThermocouples produce a measurable voltage as the surrounding temperature increases or decreases, where thermistors change their resistance to electrical current as the temperature changes. Also, thermocouples and thermistors are used in different applications, depending upon the precision needed and the temperature ranges involved.
Full Answer >A centimeter is the equivalent of 25/64 inch, and 3 centimeters is the equivalent of 1 3/16 inches. Centimeters are the smallest unit of the metric system, which is a widely used measurement system that has been adopted around the globe. The United States is the only industrialized nation in the world that has yet to adopt the metric system as its own, although it was officially sanctioned for use in 1866.
Full Answer >There are 118.11 inches, or approximately 9.84 feet, in 3 meters. Additionally, 3 meters are also equal to 3.28 yards. To convert from meters to inches, multiply a given length in meters by 39.37.
Full Answer >Three millimeters in width is approximately one-tenth of an inch. A penny is just over 1.5 millimeters, making 3 millimeters about the width of two pennies.
