What else can I help you with?
What do you call a substance that offers resistance?
A substance that offers resistance is called a resistor. It is a component in electronic circuits that limits or controls the flow of electric current.
Is it true that the bigger sized cable offers less resistance to current flow?
yes
What is the opposing force to current?
The opposing force to electrical current is resistance. Resistance is the hindrance that a material offers to the flow of electric current through it. It is measured in ohms and can be affected by factors like the material's conductivity, temperature, and length.
Which Materials which offers low resistance to flow of current is a good conductor?
All of them. That's the definition of "conductor".
What is the total opposition to current flow called?
The total opposition to current flow is called resistance. It is measured in ohms and represents the difficulty that a material offers to the flow of electric current.
Why shunt resistance must be small in ammeter?
An ammeter has to measure to current flowing through the circuit. Resistance offers an obstruction to the current flow. So, if the resistance of an ammeter is large , the current measured by the ammeter will be quite less as compared to the actual amount of current flowing through the circuit which is undesirable. If ammeter has zero resistance , then it will give the exact value of current. But this is not practically possible because every material has some value of internal resistance which we can't control. For this reason , ammeter must have small resistance
How does current work in a parallel circuit and what are its implications for the overall circuit behavior?
In a parallel circuit, current flows through multiple branches simultaneously. Each branch offers a separate path for the current to travel. This means that the total current in the circuit is divided among the branches based on their resistance. The implications of this are that devices connected in parallel receive the full voltage of the circuit, and if one branch is disrupted, the other branches can still function independently.
What terms is used to describe a wire which offers obstruction to the path of electric current?
A wire that offers obstruction to the path of electric current is typically called a resistor. Resistors are designed to limit the flow of electricity and are used in electronic circuits to manage current and voltage levels.
What offers resistance to the circuit and limits the amount of current that can flow?
The internal components of a device that has been manufactured by a company adds up to the internal resistance of the device. Some devices are higher in resistance, some are lower. The results that you can see is on the device's nameplate and is represented by the wattage that the device draws.To answer the second part of the question, the answer is Ohm's law. The current of a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. In other words if the voltage remains the same, the higher the resistance the lower the current draw. A short circuit is no resistance, very high current. This is why over current protection is needed in most electrical circuits.
How Does the length of the wire affect its resistance?
As the length of the wire increases, the resistance also increases. This is because a longer wire offers more opposition to the flow of electrical current compared to a shorter wire. Resistance is directly proportional to length, so doubling the length of the wire will double its resistance.
What type of resistance - high or low - do conductors and insulators have?
A component of a given size that offers low resistance is called a good conductor.A conductor having some appreciable resistance is called a resistor.A component of identical size that offers a higherresistance is called a poor conductor.An insulator of the same size offers even higherresistance.
What does streamlinne mean?
There is no such English words as "streamlinne". However "streamline" means to shape in such a way that the product offers the least resistance to a current, as of air or water.
