This is really easy. Calculate the total R, which is the two on the left in series, in parallel with the one on the right. Rt = 6.6•4.7/(6.6+4.7) = 2.75k the 10 mA current produces a voltage across the two sides of E = IR = 27.5 volts And that c…

10% increase is a factor of 1.1 12% decrease is a factor of 0.88 (1.1L)(xW) = LW(0.88) 1.1x = 0.88 x = 0.8 p = 20%

4x² +10x + 2 2(2x² + 5x + 1) this has no whole number or simple fraction factors.

mass of what? power of what? this is too generalized for an answer, sorry. .

I hope you mean 1N4003 and 1N4005 ?? The higher numbers in the series 1N4001 through 1N4009 are higher voltage versions, but the rest of the specs are identical, so you can always substitute a higher number part for a lower numbered one. You p…

her speed is 10 meters / 0.91s = 10.99 m/s 10.99 m/s x 1 mile/1609m x 3600s/hour = 24.5 MPH.

A square has the max area, so 4x = 30 x = 7.5 to prove, area of a rectangle is xy = A perimeter is P = 2(x+y) P = 2x+2y 2x = P - 2y 2A = 2xy 2A = (P - 2y)y 2A = Py - 2y² A = ½Py - y² differentating A' = ½P - 2y setting e…

You are correct. The fan speed switch on your dash is indeed a fan speed switch. It switches in different resistors that reduce the voltage to the fan and cause it to run at the different speeds. Changing the speed on a fan does not increase the …

Vebo is not relevant, as that junction is rarely reverse biased. It is forward biased under normal operation and under those conditions the VBE never exceeds 1 volt. But the 16 volt VCEO could be problem with a 20 volt supply. Considering the VC…

A transistor can't amplify anything unless it is biased correctly. AC or DC. So you need a bias circuit, typically a voltage divider to drive the base, an emitter resistor and a collector resistor. The emitter resistor can be bypassed with a cap …
