How do you find the value of resistance?
By Ohm's Law, resistance is voltage divided by current.
A reel of cable weighs 1279 pounds If the empty reel weighs 285 pounds and the cable weighs 7.1 pounds per foot the number of feet of cable on the reel is?
To find the number of feet of cable on the reel, first subtract the weight of the empty reel from the total weight to get the weight of the cable only: 1279 pounds - 285 pounds = 994 pounds. Then divide the weight of the cable by the weight per foot to find the number of feet: 994 pounds / 7.1 pounds/foot ≈ 140 feet. So, there are approximately 140 feet of cable on the reel.
If it takes 3127 feet of computer cable to wire an office building how much cable will be left if the wire is taken from a 5000-foot reel?
To find out how much cable will be left after wiring the office building, subtract the amount used (3127 feet) from the total length of the reel (5000 feet). So, 5000 feet - 3127 feet = 1873 feet. Therefore, there will be 1873 feet of cable left.
What will you need to measure to find out which wire has the greatest resistance?
To find out which wire has the greatest resistance, you will need to measure the resistance of each wire using a multimeter. Connect the multimeter to each wire separately and record the resistance values displayed. The wire with the highest resistance value will have the greatest resistance.
How much is1.5 sqmm per unit resistance of a cable?
The resistance of a 1.5 sqmm cable depends on its material (usually copper or aluminum) and its length. For copper, the typical resistance is about 12.1 ohms per kilometer, while for aluminum, it’s around 19.5 ohms per kilometer. To find the resistance per unit length, you would divide these values by 1000 to get ohms per meter. Thus, the resistance of a 1.5 sqmm copper cable is approximately 0.0121 ohms/meter.
What is the necessity for balancing wheatstone bridge?
just to find out our given unknown resistance value or to put it another way, To find the value of the unknown resistor attached.
When a 12 volt battery is connected across an unkown resistance there is a current of 2.5m amphere in the circuit find the value of resistance of the resistor?
4.8 ohms
What is 150 percent of 6 feet?
To find 150 percent of a value, multiply the value by 1.5. In this instance, 1.5 x 6 = 9 feet. Therefore, 150 percent of 6 feet is equal to 9 feet.
Find the length of the longest side of the rectangle is its perimeter is 25 feet?
Any value greater than 6.25 feet.
What is the maximum length for a network category 5 or 6 cable?
standard cat 5 e and cat 6 the normal cable you will find in use with you router is 100m other types of network cable vary look them up on google
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
What is the wheat stone bridge principle?
It is an circuit that is used to find the value of the resistances. The main principle behind it is the balancing an circuit by means of varying an resistance on connected to an arm of the circuit.When the resistance become equal to the variable resistance no current flows thus we can find the value of the resistance.
