resistance depends on temperature too..
we know that R=R0( 1 + rho (change in temperature) )
where
R= present resistance
R0=resisance at 00C
rho= resistivity of a material
now if the change of temperature is positive , means if the temerature increases then the resistance will also increase and vice versa
What else can I help you with?
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
Do additional resistors affect power?
Of course. Additional resistors change total resistance, which changes current, which affects power.
What are the differences between resistors connected in parallel and resistors connected in series, and how do these configurations affect the overall resistance in a circuit?
Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current passing through them. In a parallel configuration, the total resistance decreases as more resistors are added, while in a series configuration, the total resistance increases.
How does the area of series resistors affect the overall resistance in a circuit?
The total resistance in a circuit with series resistors is the sum of the individual resistances. When more resistors are added in series, the total resistance increases because the current has to pass through each resistor, making it harder for the current to flow.
Explain how the tolerance of various resistors affect the reliability of a digital circuit?
Hahn.
How does temperature affect power rating of carbon resistors?
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
How does the concept of parallel resistors connected to the same voltage source affect the overall resistance in a circuit?
When resistors are connected in parallel to the same voltage source, the overall resistance in the circuit decreases. This is because the current has multiple paths to flow through, reducing the total resistance that the current encounters.
Does the temperature of the wire affect the current?
Yes, the temperature of the wire can affect the resistance of the wire, which in turn can affect the current flowing through it. As the temperature increases, the resistance of the wire also increases, which can reduce the current flow.
How might ambient temperature may affect the resistance values you would measure in a circuit?
Ambient temperature might affect the readings of the resistance value you would measure because the resistance of some materials changes with the temperature.
What factors affect current strength in a series circuit?
The number of resistors and their value. The wire and the junction points have resistance also.
How do resistors affect current flow in an electrical circuit?
Resistors in an electrical circuit reduce the flow of current by impeding the movement of electrons. They create resistance, which limits the amount of current that can pass through the circuit.
Which factor does not affect the resistance of a material?
The factor that does not affect the resistance of a material is the color of the material. Resistance is primarily determined by factors such as the material's dimensions, temperature, and composition.
