Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it.
A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc..
depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors

What is the difference between a normal resistor and a bleeder resistor?
A resistor is a resistor. Plain and simple. By Ohm's Law, resistance in ohms is voltage in volts divided by current in amperes. The difference lies in application, not in the resistor itself. A normal resistor will introduce a voltage drop or current that makes some effect in the circuit, based on some design criteria. A bleeder resistor, on the other hand does not really affect the circuit - it is only there to "bleed off", or discharge, capacitors when the power is turned off. Consequently, a bleeder resistor will typically have a higher resistance than a normal resistor but, again, the issue is circuit design, not the resistor itself.
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
If there is a potential difference of 12 V across a resistor with 0.25 A current in it the resistance if the resistor is?
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
A battery has emf of 6 v and an internal resistance of 4 ohm it is connected to a 2.6 ohm resistor a switch when switch is open the potential difference between the terminals of a battery is?
6 volts
What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-ohm?
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.
Difference between variable and fixed resistor?
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
Why is there no flow of electric current between 2 objects of equal resistance?
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
What is the difference between resistance box rheostat and resistor?
A resistance box is a device that contains a set of fixed resistors that can be connected in various combinations to achieve different resistance values. A rheostat is a variable resistor that can be adjusted to change the resistance in a circuit. A resistor is a general term for a component that resists the flow of electrical current in a circuit and comes in fixed resistance values.
Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
How to find the potential difference across a resistor in an electric circuit?
To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.
Potential difference across resistor is doubled?
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.

What is difference between thick and thin film resistor?
Difference between thick and thin film resistor is not related to thickness but its based on how the film is applied to the surface.
Which has a highest resistance between shunt resistor and series resistor?
If you are placing more than one resistors in series, then its combined resistance is higher than when you place these resistors in shunt.
If there is a potential difference of 12 V across a resistor with 0.25 A current in it the resistance if the resistor is?
Resistance (Ohms) = Potential Difference (Volts) / Current (Amps) So, 12/0.25 = 48 Ohms.
