The total capacitance of the circuit above is?
0.25mF
0.50mF
0.75mF
1.25mF
1.50mF
Correct answer is E
CTotal in parralel = C1 + C2 + C3
CTotal = 2 + 2 + 2 → 6
C Total in series = 1 / C\(_1\) + 1 / C\(_2\)
1 / C\(_T\) = 1/2 + 1/6
1 / C\(_T\) = \(\frac{4}{6}\)
cross multiply
C\(_T\) = \(\frac{3}{2}\) or 1.5mF
What is the total resistance in the above diagram?
5 ohms
15 ohms
25 ohms
35 ohms
45 ohms
Correct answer is C
Resistance in series will be given as R = 10+10 → 20
Resistance in parallel will be given as \(\frac{1}{R}\) = \(\frac{1}{10}\) + \(\frac{1}{10}\)
\(\frac{1}{R}\) = \(\frac{2}{10}\) → \(\frac{1}{R}\) = \(\frac{1}{5}\)
Resistance in parallel = 5
Total resistance = 20 + 5 → 25ohms
