Description : If a piece of metal is 8 feet long what would the diameter be if it was bent into a circle?

Last Answer : You want the formula for the diameter (2r) if you have the circumference? If the formula for circumference is 2(pi)r, you simply do the algebra to determine r c=2(pi)r. Divide both sides of the equation by r and you have c/r=2(pi). Then divide both sides by r and you have c=2pi/r

Description : If the insulation resistance of a cable of length 10 km is 1 mega ohm, its insulation resistance for 50 km length will be

Last Answer : If the insulation resistance of a cable of length 10 km is 1 mega ohm, its insulation resistance for 50 km length will be 0.2 mega ohm

Description : What happens to the resistance of a wire when its length as well as the cross-sectional area are doubled? A) It doubles B) It becomes 4 times C) It becomes 2π times D) It remains the same

Description : lt the length, number of turns and area of a coil are  doubled, the inductance of the coil

Last Answer : lt the length, number of turns and area of a coil are  doubled, the inductance of the coil is quadrupled

Description : What is channel length modulation in MOSFET?

Last Answer : Shortening of lenght of the inverted channel region with increase in drain bias for large drain biases due to which current increases with drain bias and output resistance decreases is called channel length modulation in MOSFET.
