Given Information:
Resistance = R = 250 Ω
Voltage = V = 3 V
Tolerance = ±5%
Required Information:
Maximum current = Imax = ?
Minimum current = Imin = ?
Answer:
Imax = 12.6 uA
Imin = 11.4 uA
Explanation:
As we know from Ohm's law
I = V/R
The current will be maximum when R is minimum and the current will be minimum when R is maximum
Rmax = 250,000 + 0.05*250,000
Rmax = 250,000 + 12500
Rmax = 262500 Ω
Rmin = 250,000 - 0.05*250,000
Rmin = 250,000 - 12500
Rmin = 237500 Ω
Imax = V/Rmin
Imax = 3/237500
Imax = 12.6 uA
Imin = V/Rmax
Imin = 3/262500
Imin = 11.4 uA
Answer:
c. Force is not necessary for maintaining motion
I believe this is the correct answer, hope this helps :)
Explanation:
Frequency is no. of times this wave vibrates or complete its one cycle per unit time. As it vibrates 30000 times per second its frequency is 30000 per second or 30000 Hz [1 Hz = once per second].
