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.
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.
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.
B - Dynamic resistance
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
a box which has resistance between 1 ohm to 50000 ohm
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.
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.
we use it when we require a variable resistance in a circuit
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.
The factor that does not affect the resistance of a material is the color of the material. Resistance is primarily determined by factors such as the material's dimensions, temperature, and composition.
yes, calculate it from temperature coefficient of resistance.
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.
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.
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.
The internal composition or material of an object does not affect air resistance. Air resistance is mainly determined by an object's size, shape, and speed when moving through air.
Depends on the type of rubber and its composition. Rubber generally is an insulator
