a box which has resistance between 1 ohm to 50000 ohm
What else can I help you with?
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 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.
Does plastic have a high resistance?
Yes, it has a high resistance as it is an insulator.
Do Dead batteries have high internal resistance?
yes, batteries have high internal resistance. The higher the resistance the lower power you get out of the batter. Therefore if you no power you have very high 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.
How high is your body resistance?
Your body resistance is high- hard to push electrons through.
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
What is high resistance what is low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
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.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
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.
