Question

sin (40- theta) -sin(59-theta)+cos^2 40 + cos^2 50 /sin^2 40 + sin^2 50 =2 ​

Answer 1

Answer:

For parallel combination, C

eq

=C

1

+C

2

+C

3

=(2+3+4)pF=9pF

(b) q=V×C

for parallel array, V remains the same across each capacitor.

for C=2 pF

q

1

=VC=100×2×10

−12

=2×10

C

for C=3 pF

q

2

=VC=100×3×10

−12

=3×10

C

for C=4 pF

q
