# What does resistance mean - Answers.

In electronics and electromagnetism, the electrical resistance of an object is a measure of its opposition to the flow of electric current. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction. The SI unit of electrical resistance is the ohm, while. Series and Parallel Circuits. 7-10-00 Section 19.1 Series circuits. A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: equivalent resistance of resistors in series: R.

## What does resistance mean? - definitions.

In aerodynamics, drag (sometimes called resistance) is a force which tends to slow the movement of an object through a liquid or gas.As a moving object pushes the liquid or gas out of its way, the fluid pushes back on the object. This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.If you look at the typical product description of a resistance band (Amazon is a good place to see a lot of these), you'll see that nearly all of them give a range of resistance. For example, one band might say 25-80 lbs of resistance while another says 50-125 lbs.The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through a substance. It explains the relationship between voltage (amount of electrical pressure) and the current (flow of electricity). With more resistance in a circuit, less electricity will flow through the circuit. The inverse of resistance is conductance, a measure not much.

Money-back guarantee in case you do.In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which. What does resistance mean? You have already seen the video on the topic of the research projects of Georg Ohm in class. The next video will give you a short overview on the three electrotechnical basic quantities voltage, current and resistance. Source: YouTube.

## What does effective resistance mean? What is the. What is Air Resistance? Air resistance the friction that occurs between air and another object.It is the opposing force that the object experiences as it passes through the air. Air resistance and gravity are the two fixed forces of nature which move on any object lifted from the earth and moved through the air. For example, when a plane flies through the air, the air particles are resisting. When the length of the wire decreases, the resistance decreases as the length is less. The Resistivity of Various Materials. A material with high resistivity means it has got high resistance and will resist the flow of electrons. A material with low resistivity means it has low resistance and thus the electrons flow smoothly through the material. Resistance is the opposition that a substance offers to the flow of electric current. It is represented by the uppercase letter R. The standard unit of resistance is the ohm, sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega. Conductance is the reciprocal of resistance. It is a measure of how much current flows when there is a pd of 1 volt across the component units: siemen. Negative resistance is used where an increase in the PD causes a reduction in the current flow. What does the alpha symbol mean in physics? The letter alpha represents various concepts in physics and chemistry, including alpha radiation, angular acceleration, alpha particles, alpha carbon and strength of electromagnetic interaction (as Fine-structure constant).

## What does air resistance mean? - Definitions.net. Resistance to something such as a change or a new idea is a refusal to accept it.
