To provide 240 ohms of resistance.

What those 240 ohms do in an actual circuit depends on the intention of the designer.

When Resister is 120 volts and the current through the resister is 0.5 Amps determine the value of the resistor in ohms?

Using Ohms Law, the answer is 120/0.5 = 240 Ohms.


What are resistor values defined by?

Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.


How do you determine shorted resistor?

A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.

What is the largest value the resistor can be and still be in tolerance?

To determine the largest value a resistor can be while still being in tolerance, you need to know the resistor's nominal value and its tolerance percentage. For example, if a resistor has a nominal value of 100 ohms with a tolerance of 5%, the maximum allowable resistance would be 100 ohms + (5% of 100 ohms), which is 105 ohms. Thus, the largest value the resistor can be while remaining in tolerance is 105 ohms.


A series circuit has individual resistor values of 200 ohms 86 ohms 91 ohms 180 ohms and 150 ohms What is the total resistance of the circuit?

In a series circuits, you simply add the the values of each resistor and that is you answer. i.e. - 200 + 86 + 91 + 180 + 150 = 707 ohms


Does an open resistor measure 0 ohms?

No, an open resistor has a value of infinity. An open resistor typically will measure over 900 Megohms. A zero ohm resistor is exactly that, and will measure zero ohms. They are typically surface-mount devices.


Is resistor measured in amps?

No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
