Sort of.
Resistance of a wire is usually given as "so many" oms per foot (or meter, etc).
To actually determine a wire's resistance you would need a sensitive ohmmeter,
OR a known voltage source and an ammeter.
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.
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.
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.
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.
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.
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.
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.

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)

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.
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.
The Mohs mineral hardness scale.

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.
Copper is the main metal used for this purpose.
