It is used to dial in a specific resistance within the range of the box. It can be used wherever you need a resistor of an unknown value or a precise value. Most decade boxes provide reistance with .01% of the desired resistance. I've used them to balance a wheatstone bridge that had a tiny mV offset.
What else can I help you with?
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.
What is decade capacitance box?
same as decade resitance box but instead of reitances there wil be capacitances
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.
What symbol is often used for electrical resistance?
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
Why rotor contactor in external resistance of slipring motor connected in delta?
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.
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.
How do you use resistance decade box?
we use it when we require a variable resistance in a circuit
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.
What is a resistor decade box?
A box of precision resistors where you can dial in the exact resistance you want with dials. Essentially a variable resistor with very precise, discrete, settings.
What is decade capacitance box?
same as decade resitance box but instead of reitances there wil be capacitances
What is high resistance box?
a box which has resistance between 1 ohm to 50000 ohm
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.
What Does Chinc mean?
I got it for an honesty box answer. The question was, "what decade am i fitted to live in"
How do you calculate resistance box for slip ring motor?
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the 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 are the applications of decade resistance box?
A decade resistance box is piece of laboratory equipment that allows the user to dial in a precise amount of electrical resistance to be inserted into a circuit. For example, it might have a dial for 100s of Ohms, 10s of Ohms, and 1s of Ohms, and allow the user to set any value from 999 Ohms to 0 Ohms in 1 ohm steps. While the use of this device has probably been largely superseded in laboratory use by more sophisticated equipment, it was used in the past in some or all of the following applications: Measurement of unknown resistances by the "bridge" method, Setting the current in a test circuit, Calibrating other lab equipment such as an Ohmmeter or Ammeter, Demonstrating Ohm's Law, and so on.
Command conquer first decade?
Command & Conquer: The First Decade was a box set of games that included every game in the Command & Conquer series until then. umm okay...
