What resistance of a connecting wire is less than the resistance of a resistor?
The resistance of a connecting wire that is less than the resistance of a resistor would depend on the materials and dimensions of the wire and resistor. Generally, most connecting wires have very low resistance compared to resistors. Copper wires, for example, have low resistance and are commonly used for connecting circuits.
What does a thermister do and how does it function in a circuit?
A thermistor is a type of resistor that changes its resistance with temperature. In a circuit, a thermistor is used to measure temperature by detecting the change in its resistance. When the temperature changes, the resistance of the thermistor changes, which can be measured and used to determine the temperature in the circuit.
How does the length of a wire affect the resistance?
Yes, resistance is directly proportional to the length, and inversely proportional to the cross sectional area. R = p*l/A. Where R is the resistance of the piece of conducting material, p is Greek letter rho, representing the resistivity of the material, l (lower case L) is the length, and A is the area.
What wires in a ciruit are made of material that is a doortuccn?
Copper wires are commonly used in circuits as they are a good conductor of electricity. Copper is a ductile material that allows easy shaping into wires and has low resistance, making it ideal for carrying electrical current efficiently in a circuit.
Is vernier caliper used to measure length or mass?
A vernier caliper is used to measure length, not mass. It is a precision measuring tool commonly used in engineering, metalworking, and other fields to accurately determine the dimensions of an object with high precision.
How can a multimeter be used to test wires effectively?
A multimeter can be used to test wires effectively by setting it to the appropriate mode (such as continuity or resistance), placing the probes on each end of the wire, and checking for a complete circuit or a specific resistance reading. This helps to determine if the wire is functioning properly or if there is a break or short circuit.
Why are wires with high resistance used in light and toasters?
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
Why are wires with high resistance used in light bulbs and toasters?
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
Is resistivity the same for all materials with the same length?
Yes, because the resistivity does not depends on the length of any materials. Resistivity is constant.-Ariel DUmancas-No. The resistance in different materials is different. For example, Copper has a low resistance to electricity compared to plastic. This is also one reason why copper is used instead of plastic in wires. Knowing the resistance of different material helps decide what material should be use for different objects (like copper for wires in plastics)

How do you find the perimeter of a triangle if you only know the angles and one of the lengths?
The law of tangents can be used to determine another side length; the sine rule can then be used to determine the third side length.
What is dynamic resistance and give you brief account about it?
A device's resistance to electricity, like in a wire's resistance to having electricity flowing through it, copper has very little, so that's why copper is used in wires.
What is used to determine a mineral's resistance to being scratched?
The Mohs mineral hardness scale.
A unit of measurement used to determine length?
meter, inch, yard
Does the resistance of a conductor incfrease by any measure when the conductor is in doubled in length?
The resistance is directly proportional to the length of conductor and inversely proportional to area of the cross section.If the length is doubled then the resistance will double.Resistance=rho*l/arho=resistivity of the material (Ohms/m) and depends on the material used for the wirel=length of the wirea= area of the cross section of the wire.
What metal conducts electricity well and is used for wires and pipes?
Copper is the main metal used for this purpose.
What is twist length used for in network cabling?
To combine two wires that will look like one wire
