Question

In all of the pictures below, the input to the oscilloscope is a sine wave. Indicate on the blank line which adjustment is required for each picture.
A 5 uF capacitor is charged to 10 volts and then connected to a 10 Megaogm resistor. What will the remaining voltage be after 150 seconds? s In all of the pictures below, the input to the oscilloscope is a sine wave. Indicate on the banks line which adjustment is required for each picture. A. Vertical Position C. Focus E. Time/div B. Horizontal Position D. Vertical volts/div F. Trigger A 5 uF capacitor is charged to 10 volts and then connected to a 10 Megaohm resistor. What will the remaining voltage be after 150 seconds?

Explanation / Answer

4)
1st diagram --> A. vertcal position

2nd diagram --> C.Focus

3rd diagram --> D. Verticalvolts/div

4th diagram --> E.Time/div

5)

given

C = 5 micro F

Vmax = 10 volts

R = 10 Mega ohm

Time constant of the ckt, T = R*C

= 10*10^6*5*10^-6

= 50 s

at time, t = 150 s,

Voltage across capacitor, V = Vmax*e^(-t/T)

= 10*e^(-150/50)

=10*e^(-3)

= 0.498 V
