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.
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.

Dc resistance of diode is a static resistance b dynamic resistance c high resistance d zero resistance?
B - Dynamic resistance
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
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 there any change in resistance of carbon composition resistor due to change in temperature?
yes, calculate it from temperature coefficient of resistance.
Does a longer wire equal resistance?
Wire is not equal to resistance. If you have two pieces of wire with the same thickness, composition, and temperature, the longer piece has higher electrical resistance.
How do you use resistance decade box?
we use it when we require a variable resistance in a circuit
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 are propertys of rock?
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.

How do you improve creep resistance in an alloy?
increase of creep strength by optimization of the chemical composition of an alloy.
How much electrical resistance is in rubber?
Depends on the type of rubber and its composition. Rubber generally is an insulator
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.
