What are some facts about resistance?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature.
What is the topic of resistance?
Resistance is the hindrance to the flow of electrons in material. 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.
What does it mean when there is no resistance?
Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.
What are two types of resistance?
Resistors can be broadly of two types. Fixed Resistors and Variable Resistors.
What is resistance and its formula?
Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A. There is a voltage or IR drop across a resistor, caused by the current flowing through it, given by V = IR.
What is an example of resistance?
The act or an instance of resisting or the capacity to resist. Resistance is defined as a refusal to give in or to something that slows down or prevents something. An example of resistance is a child fighting against her kidnapper. An example of resistance is wind against the wings of a plane.
Which is directly proportional to the resistance?
The resistance of any conductor is directly proportional to length and inversely proportional to area of cross-section of the substance. As value of resistance(R) is directly proportional to length of resistance, so by increasing the length of resistance the value of resistance increases.
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 the difference between continuity and resistance?
Think of it this way: Continuity is a binary version of resistance. If the resistance of the thing we’re testing—the wire we want to make sure isn’t broken, the connection we want to be certain actually goes to ground, the switch we want to know works—is low (like less than 1 ohm), we say that it has continuity.
What is an example of a resistance?
How do you deal with resistance to change?
A solution which has become increasingly popular for dealing with resistance to change is to get the people involved to “participate” in making the change. But as a practical matter “participation” as a device is not a good way for management to think about the problem.
When does resistance to change occur in an organization?
The range of reactions, when change is introduced, is unpredictable. No employee is left unaffected by most changes. As a result, resistance to change often occurs when change is introduced. Resistance to change is best viewed as a normal reaction. Even the most cooperative, supportive employees may experience resistance.
What are the themes of resistance to change?
The first of the two major themes of the article is that resistance to change does not arise because of technical factors per se but because of social and human considerations. This statement still seems to be true.
Why are so many people resistant to change?
Change is uncomfortable and requires new ways of thinking and doing. People have trouble developing a vision of what life will look like on the other side of a change. So, they tend to cling to the known rather than embrace the unknown. Employees don’t fear change, though, they fear the unknown. They fear being changed.
