The current in the circuit will be equal to (10 - 3j)/(4 + j) when the voltage is 10 - 3j and impedance is 4 + j.
<h3>What is Electrical energy?</h3>
When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge.
As per the given information in the question,
Voltage, E = 10 - 3j
Impedance, Z = 4 + j
Then, the value of current will be,
E = IZ
I = E/Z
I = (10 - 3j)/(4 + j)

Answer:
2(3n)
Step-by-step explanation:
so you need to get the length of two side first!
the first side is <em>n</em> and the second is 2 times bigger so it means the length of the second side is <em>2n</em>
after you add them together you can get <em>3n</em>, so just times 2 for the whole square!
so you can get 2(3n) now!
hope it'll help! good night!

Step-by-step explanation:
Answer:
<u>131 seats</u> are in the 30th row.
Step-by-step explanation:
The theater is designed with the first row there are 15 seats, in second row 19 seats and in the third row there are 23 seats.
Now, to find the number of seats in the 30th row.
So, we get the common difference(
) from the arithmetic sequence first:
Thus, 
So, the first tem 
= 15.
The number of last row (
) = 30.
Now, to get the number of seat in the 30th row we put formula:
Therefore, 131 seats are in the 30th row.
