What is the use of resistance box?

The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.


How do you use resistance decade box?

we use it when we require a variable resistance in a circuit


What is high resistance box?

a box which has resistance between 1 ohm to 50000 ohm


What is a resistance decade box?

Resistance decade box is nothing but Resistance bank. It has various ranges of Resistance value ranging from few ohms to few mega ohms. In other terms, large value of resistance are fabricated in single box is said to be Resistance decade box.


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 calculate resistance box for slip ring motor?

Why the wires in the resistance box are double folded?

The wires in the resistance box are double folded to reduce their resistance value by a factor of 4, as resistance is inversely proportional to the cross-sectional area of the wire. This allows for more precise resistance increments to be achieved by varying the length of wire exposed in the circuit.


What is the difference between resistance box and rheostat?

Resistance box will provide resistance of discrete values such as 1, 2, 3 ohms or 0.1,0.2, 0.3 ohms. So interim values are not possible. But rheostat gives a chance to vary the resistance continuously. It may be 5 ohm or even 5.769 ohm. So just to fix current for a specified value such 1.5 ampere resistance box will not be suitable where as a rheostat is the most suitable.


Why does it take more force to move a heavy box then a light box?

It takes more force to move a heavy box because the heavier box has more mass, which means it has more inertia. Inertia is the resistance of an object to changes in its motion, so it requires a greater force to overcome this resistance and move the heavy box compared to the light box.


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.


Use the word resistance in a sentence?

Resistance is futile!


Can you use resistance in place of diode in clipping circuits?

no we not use resistance in place of diode.
