Resistance Examples
Resistance examples
Because of the nature of generating heat when conducting current, resistors are used in a heater, toaster, microwave, electric stove, and many more heating appliances. In a light bulb, the metal filament glows white-hot due to the very high temperature produced from the resistance when electricity is passed through it.
What is resistance simple words?
Resistance is the opposition that a substance offers to the flow of electric current.
What is resistance in a person?
Resistance means "refusal to comply with or accept something." An individual person can put up resistance against something she disagrees with or doesn't want to participate in.
What is resistance in physics with example?
Resistance refers to the amount that an object impedes or resists in an electric current. Electric current refers to the flow of electrons. An easier way to explain resistance is to consider an example of a person in a crowded market struggling to go from one shop to another.
What are 5 examples of resistors?

What are resistors give some examples?
A resistor is a device that shows resistance of a passage of electric current. For example, ohmic resistors. Resistors can be of a fixed value, for example: 100 Ohms, (100Ω) or variable as in 0 to 100Ω.
How do you use resistance in a sentence?
Noun They have shown a stubborn resistance to change. The troops met heavy resistance as they approached the city. The paint shows good weather resistance. Over time the patient could develop a resistance to the drug.
What is resistance used for?
Resistance serves as an indicator that quantifies how readily current will flow in a circuit using ohms (Ω) as the unit. Current increases when resistance decreases, and it decreases when resistance increases. Resistors are essential in order to ensure that current flows at the appropriate level in circuits.
What causes resistance?
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
What is an example of resistance in therapy?
In psychoanalysis, resistance is loosely defined as a client's unwillingness to discuss a particular topic in therapy. For example, if a client in psychotherapy is uncomfortable talking about his or her father, they may show resistance around this topic.
What is an example of rolling with resistance?
Ways of rolling with resistance that you could try are: Just listen reflectively - Respond to what the person is saying by paraphrasing, summarising or reflecting it back to them in a way which shows that you have heard what they are saying, even if you don't agree with it.
How do you deal with resistance?
How to Overcome Resistance and Effectively Implement Change
- Overcome opposition. Regardless of how well companies manage a change, there is always going to be resistance.
- Effectively engage employees. Listen, listen, listen. ...
- Implement change in several stages. ...
- Communicate change effectively.
What is resistance and its types?
Resistance is designated with R and its unit is the ohm (Ω). A resistor is a device designed to produce resistance. Resistors can be used to limit current, divide voltage, or generate heat. There are two main types of resistors: fixed and variable.
How do you calculate resistance example?
That's just going to be equal to r1 plus r2 plus r3 effectively all we do is add up all of these
How do you find the resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
What household items have resistors?
Appliances such as electric heaters, electric ovens, and toasters all use resistors to turn current into heat, then using the heat lost from this resistor to warm the surrounding area.
Is a TV a resistor?
The TV is not a resistor so Ohm's law does not apply to it.
Is a light bulb a resistor?
The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a resistor.
What are common resistors?
The most common series are:
- E6 20% tolerance.
- E12 10%
- E24 5% (also available with 1%)
- E48 2%
- E96 1%
- E192 0.5% (also used for resistors with 0.25% and 0.1%).
What is difference between resistance and resistivity?
Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.
