Question
Can someone please let me know if I've done these problems correctly? I'd really appreciate some feedback and help!!
!
1. Point A = 8V
Point C is 0V (because it is at ground), Point B is 3V because it's 3ohms from C, Point A is 8V because it's 5ohms + 3ohms, and Point D is -2V because it is 2ohms down from Point C.
2. 2.5A
I=VR ----> I=10V/4ohms = 2.5A
3. I've done a simple drawing of the circuit where the ammeter is in series with R ("a" inside a bubble above the R) and where the voltmeter is in parallel with R("v" inside a bubble in parallel, to the right of R).
4. I need some help with this one!
5. 0.003nF
Dielectric constant (k) = (with dielectric) / (without dielectric)
15 microfarads = 1.5x10^7 Farads *converted microfarads to farads*
1.5x10^7 Farads = 0.015nF *converted the farads to nano farads*
k= (0.015nF) / (5nF) = 0.003nF
Explanation / Answer
15 microfarads = 1.5x10^-6 Farads
