Answer:
-I₁ + I₂ + I₃ = 0
I₁ = I₂ + I₃
Step-by-step explanation:
The image of the circuit is obtained online and attached to the question.
The junction rule is essentially a law of conservation of current (charges). It applies to electrical circuits at steady state.
It explains that the for any given junction (node in an electrical circuit), the sum of current entering the junction is equal to the sum of current leaving the junction. That is, the net sum of current at any junction is zero.
Current entering a junction is assigned a positive sign and that leaving the junction is assigned a negative sign.
Σ I = 0
From the image of the circuit attached, I₁ is leaving the junction labelled number 1 and I₂ and I₃ are entering the junction.
Hence,
-I₁ + I₂ + I₃ = 0
I₁ = I₂ + I₃

49/64 you divide the numerator and denominator by 2 hope this helped
Answer:
x+79degree + 35degree = 180 degree ( being the sum of all angle of the triangle )
or, x + 114 degree = 180 degree
or, x = 180degree - 114degree
or, x = 66degree
hence, x = 66 degree.
Answer:
There are 1084 pupils in that school.
Step-by-step explanation:
If there are 542 girls and boys then you would have to double 542 to get the total number of people. So, there are 1084 people in that school.
Hope this helps!
Answer:
Step-by-step explanation:
Let L represent the Length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
Then substitute 12 in for the length and 6in for the width. It becomes.
Perimeter = 2(12 + 6).
Perimeter =2 × 18 = 36
