Definition: Resistance(Represented by R) offers hindrance to the flow of current in an electrical circuit. It is measured in ohms, which is named after its developerGeorge Simon Ohm. He is a German physicist, who has studied the relationship between voltage, current andresistanceand tells us th...
While a potential difference across the conductor encourages the flow of electrons, resistance discourages it. The rate at which charge flows between two terminals is a combination of these two factors. If two different conductors are placed in a circuit, then the amount of current found to ...
The resistance value is specified in ohms, the standard symbol is “R” orΩ. Resistor values are often stated as “k” (kilo, or times 1,000) or “M“, (meg, or times 1,000,000) for convenience. There are a few conventions that are followed, and these can cause problems for th...
Learning to work with resistors is important in electronics. One fundamental skill you should learn is how to use Ohm’s law. It describes the relationship between the voltage, resistance, and current: V = R * I V is the symbol for voltage. I is the symbol for current. R is the symbo...
immunodeficiency virus (AIDS virus, HIV). After AIDS virus invades the human body, it can destroy the immune system of the human body, make the infected people gradually lose their resistance to various diseases, and ...
The initial current is limited by the resistance of the wires, or perhaps by a real resistor. But as charge builds up on the plates, charge repulsion resists the flow of more charge and the current is reduced. Eventually, the repulsive force from charge on the plate is strong enough to ...
Resistor Symbol What is Resistance? The resistance can depend on theOhm’s lawwhich is discovered by the German physicist namely “Georg Simon Ohm”. Ohms Law TheOhm’s lawcan be defined as; the voltage across a resistor is directly proportional to the current flow through it. The Ohms law...
If resistance is the word we use to symbolize the measure of how difficult it is for the current to flow, then a good word to express how easy it is for the current to flow would be conductance. Mathematically, conductance is the reciprocal, or inverse, of resistance: ...
Token resistance. Symbol A thing considered the embodiment of a concept or object. The lion is the symbol of courage; the lamb is the symbol of meekness or patience. Token Being a product of tokenism; merely symbolic Refused to be the token woman on the committee. Symbol (linguistics) A ...
Opposition is a broader term for any form of dissent or disagreement, whereas resistance specifically implies an act of defying or combatting an influence or force.
