<u>Answer</u>-
<em>The total capacitive reactance of the circuit is </em>442.10<em> Ω.</em>
<u>Solution-</u>
Three capacitors, a 12 mF, a 20 mF, and a 30 mF, are connected in series to a 60 Hz source.
The effective/equivalent capacitance of the circuit is,
When capacitors are joined in series, the total value of capacitance in the circuit is equal to the reciprocal of the sum of the reciprocals of capacitance of all the individual capacitors.
We know that,
Where,
= Capacitive Reactance (in Ω)
f = frequency (in Hz)
C = Capacitance (in F)
Here given,
= ??
f = 60 Hz
C = 6 mF = F
Putting the values in the formula,
Therefore, the total capacitive reactance of the circuit is 442.10 Ω.
Yes! The smaller trapezoid is being turned into the bigger one. Take 10.5 and divide that by 7. This would be 1.5. You can double check your work with 15 divided by 10.
Answer = 1.5
40.25 is 40 1/4 as a decimal
There is two ways to do this
4+4+4 = 12
or
4*3=12
either way the answer is 12 4*3 is just like a shortcut of writing it out instead of having to add the numbers together. When it is "4 times 3" it is saying what is the sum of 4 added 3 times? another example can be 9*9 which is like the simplified version of 9+9+9+9+9+9+9+9+9= 81 9*9 = 81 which is the same thing. try this with other numbers and you will see that it will all result the same way.
* = times or "x" which is the multiplication sign
