Quick Answer: What Is An Example Of Resistance?

What are three types of change?

The three types of change are: static, dynamic, and dynamical..

What is the law of resistance?

The following are the main laws of resistance: (i) Resistance of a conductor is directly proportional to its length, provided temperature and other physical conditions remain unchanged. … (ii) Resistance of a conductor is inversely proportional to its area of cross section, other conditions remaining the same.

What is electrical resistance simple words?

The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through a substance. … With more resistance in a circuit, less electricity will flow through the circuit. The inverse of resistance is conductance, a measure not much used.

How do you use resistance in a sentence?

Use “resistance” in a sentence | “resistance” sentence examplesThe no-smoking policy was introduced with little resistance from staff.The enemy resistance thinned out as night approached.As with all new ideas it met with resistance.They mounted stiff resistance to the proposal.More items…•

Where are resistors used in real life?

A resistor is a device used to regulate the amount of electric current in a circuit. Resistors are used in light bulbs and appliances to limit the amount of current that reaches them. They work by resisting the flow of current through the circuit.

What are the most common forms of resistance?

“Day-to-day resistance” was the most common form of opposition to slavery. Breaking tools, feigning illness, staging slowdowns, and committing acts of arson and sabotage–all were forms of resistance and expression of slaves’ alienation from their masters. Running away was another form of resistance.

How do I measure resistance?

How to Measure Resistance with a Digital MultimeterTurn power to circuit OFF. … Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below). … First insert the black test lead into the COM jack.Then insert the red lead into the VΩ jack.More items…

How is resistance used in everyday life?

Resistors are electrical components in an electric circuit that slow down current in the circuit. … 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.

What are the two types of resistance?

Resistors can be broadly of two types. Fixed Resistors and Variable Resistors.

What are the causes of 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 happens to the current as the resistance increases?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

What are the three types of resistance?

We call these three types of resistance: game change, outside game and inside game. This section will explain what makes each type of resistance effective, as well as how they complement one another.

Whats does resistance mean?

resistance. [ rĭ-zĭs′təns ] A force, such as friction, that operates opposite the direction of motion of a body and tends to prevent or slow down the body’s motion. A measure of the degree to which a substance impedes the flow of electric current induced by a voltage. Resistance is measured in ohms.

What is resistance and uses?

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
