Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
How do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
In a parallel circuit the smallest resistor is 500 ohms. What is the largest value this parallel circuit can have?
500 ohms.
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
In a parallel circuit total circuit resistance is always?
In a parallel circuit, the total circuit resistance is always less than the resistance of the smallest individual resistor in the circuit. This is because the total resistance is calculated using the reciprocal formula: ( \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + \ldots ). As more resistors are added in parallel, the total resistance decreases, allowing for more current to flow through the circuit.
How do resistance behave in parallel circuit?
in a parallel circuit resistance decreases increasing the current.

What device has the smallest current in parallel circuit?
In a parallel circuit, each branch has its own current flow, so there isn't a single device that has the smallest current. The current through each device is determined by its resistance and voltage applied. The device with the highest resistance will have the smallest current flowing through it in a parallel circuit.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
What is the total impedance of a circuit with a capacitor in parallel with a resistor?
The total impedance of a circuit with a capacitor in parallel with a resistor is calculated using the formula Z 1 / (1/R 1/Xc), where Z is the total impedance, R is the resistance of the resistor, and Xc is the reactance of the capacitor. This formula takes into account the combined effects of resistance and reactance in the circuit.
Will putting another resistorin parallel raise or lower the total resistors in circuit?
Placing another resistor in parallel to an existing resistor will lower the total resistance in the circuit. RParallel = 1 / Summationi=1toN (1 / Ri)
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
Does the highest or lowest resistance dominate a parallel circuit?
The total effecive resistance of several individual resistances in parallel is less than the smallest individual resistance, so in that sense I guess you'd have to say that the lowest resistance 'dominates' the character of the whole parallel circuit.
