Question

what is the effective capacitance of 2 conductor of capacitance 3 microfarads and 4 microfarads when connected in series and parallel​

Answer 1

Explanation:

1). (The small children)= SUBJECT

( were throwing stones at the dogs )= (PREDICATE)

2). (Gita) = SUBJECT

(Was dancing gracefully) = PREDICATE

3). (My five year old brother) = SUBJECT

(Was thrilled when he got a as a gift)= (PREDICATE,)

4). (my baby brother) and (my mother)= SUBJECT

(leaving for a moment) and (went into the kitchen)= PREDICATE

5). (The good news ) = SUBJECT

(is that our school won the trophy) = PREDICATE

Answer 2

They are as shown below:

For capacitor C1, C2 in parallel we have:

$\\\tt \: C_{net} = C_{1} + C_{2}$

Using the values give,

$\\\tt \: C_{net} = (3 \times 10^{ - 6} ) + (4 \times 10^{ - 6} ) \\ = { 10}^{ - 6} (3 + 4) \\ = 7 \times {10}^{ - 6} C$

For Capacitor in series:

$\\\tt \dfrac{1}{C_{new}} = \dfrac{1}{C_{1}} + \dfrac{1}{C_{2}} \\\tt = \dfrac{1}{3 \times {10}^{ - 6} } + \dfrac{1}{4 \times {10}^{ - 6}} \\ = \frac{7 \times {10}^{ - 6} }{12 \times {10}^{ - 12} }$

$\\\tt \: C_{new} = 1.4 \times {10}^{ - 6} C$
