what is a resistance

- There is another important property that can be measured in electrical systems. This is resistance, which is measured in units called ohms. Resistance is a term that describes the forces that oppose the flow of electron current in a conductor. All materials naturally contain some resistance to the flow of electron current. We have not found a way to make conductors that do not have some resistance. If we use our water analogy to help picture resistance, think of a hose that is partially plugged with sand. The sand will slow the flow of water in the hose.

Colony  (TV series) The term resistance is generally used to designate a movement considered legitimate (from the speaker's point of view). Organizations and individuals critical of foreign intervention and supporting forms of organized movement (particularly where citizens are affected) tend to favor the term.

PHYSICS CH 4 Inertia is the resistance of any physical object to any change in its state of motion including changes to its speed and direction or the state of rest. It is the tendency of objects to keep moving in a straight line at constant velocity.

- Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a … electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc..otal resistance in the circuit decreases   Two resistors in parallel have less overall resistance than the same two resistors in series, or even just one of the resistor … s by itself. This is because two resistors in parallel draw more current than just one resistor -- assuming constant voltage.

Resistors That's why we define resistance more precisely as the voltage in volts required to make a current of 1 amp flow through a circuit. If it takes 500 volts to make 1 amp flow, the resistance is 500 ohms (written 500 ω). You might see this relationship written out as a mathematical equation: V = I × R.

Rebellion Rebellion, uprising, or insurrection is a refusal of obedience or order. It refers to the open resistance against the orders of an established authority. The term comes from the Latin verb rebellō, I renew war (from re- (again) + bellō (I wage war/I revolt). The rebel is the individual that partakes in rebellion or rebellious activities, particularly when armed. Thus, the term rebellion also refers to the ensemble of rebels in a state of revolt. A rebellion originates from a ...

Resistance training â health benefits Resistance training (also called strength training or weight training) is the use of resistance to muscular contraction to build the strength, anaerobic endurance and size of skeletal muscles. Resistance training is based on the principle that muscles of the body will work to overcome a resistance force when they are required to do so. When you do resistance training repeatedly and consistently, your muscles become stronger.

Voltage, Current, Resistance, and Ohm's Law Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current). So, when we talk about these values, we’re really describing the movement of charge, and thus, the behavior of electrons.

About Resistance Antibiotic / Antimicrobial resistance is the ability of microbes to resist the effects of drugs – that is, the germs are not killed, and their growth is not stopped. Although some people are at greater risk than others, no one can completely avoid the risk of antibiotic-resistant infections.

opposition Opposition is something that goes against or disagrees with something or someone else. Just about any political view has opposition. Chances are you know the word opposite: this means something similar. The opposition to something goes in the opposite direction. There is always opposition to raising taxes in this county. The Republicans are the opposition of the Democrats (and vice versa). If you're holding a meeting, you could say, Is there any opposition to this idea? In war, the enemy is the opposition, and in a debate, the other speaker is the opposition. Whenever there's disagreement or confrontation, there's opposition. Thesaurus

Difference Between Resistance and Impedance Impedance is a the measure of opposition to an alternating current (AC) while resistance usually refers to direct current (DC). 2. Resistance is simple while Impedance will consider reactance in addition to resistance to determine it. 3. Resistance is pure ohmic impedance (absence phase shift).

- Resistance refers to the property of a substance that impedes the flow of electric current. Some substances resist current flow more than others. If a substance offers very high resistance to current flow it is called an insulator. If its resistance to current flow is very low, it is called a conductor.
