Answer: 3A
Explanation:
First, we must calculate voltage by summing the reciprocal of the resistances in the circuit
1/40 +1/40 = 2/40 = 1/20 = 1/R, so R = 20Ω
Using Ohm's Law, I = V/R, so the current I is I = 120/20 = 6A
Using Kerchoff's Circuit Law, we know that current will split evenly at a junction, so each resistor will get one half, or 3A.

Explanation:
lolllll i need points sorry
- The equivalent capacitance between point a and b is 5.87μf.
- The charge at 20μf is 93.92 μC.
- The charge at 6μf is 67.8 μC.
- The charge at C and 3μf is 26.12 μC.
<h3>
Sum of capacitance of C and 3μF</h3>
The sum of the capacitance is calculated as follows;
1/Ct = 1/C + 1/3
1/Ct = 1/10μf + 1/3μf
1/Ct = (3μf + 10μf)/30μf²
1/Ct = 13μf/30μf²
Ct = 30μf²/13μf
Ct = 2.31μf
<h3>Total capacitance in parallel arrangement</h3>
The total capacitance in parallel arrangement is calculated as follows;
Ct = 2.31μf + 6μf = 8.31μf
<h3>Equivalent capacitance between point a and b</h3>
1/Ct = 1/8.31μf + 1/20μf
1/Ct = 0.1703
Ct = 5.87μf
<h3>Charge flowing in each capacitor</h3>
Maximum voltage is delivered in 20μf, q = CV
<u>charge for 20μf:</u>
q = (5.87 x 16)μC
q = 93.92 μC
<h3>Equivalent capacitance for C, 3μf and 6μf</h3>
Ct = 2.31μf + 6μf = 8.31uf
<u>charge for 6μf:</u>
q = (6/8.31) x 93.92μC
q = 67.8μC
<h3>Total charge for C and 3μf</h3>
q = 93.92μC - 67.8μC = 26.12 μC
charge for C = charge 3μf = 26.12 μC

Answer:
Dalton's atomic theory
Explanation:
Dalton's atomic theory was the first to introduce the idea that all things are made from indivisible spheres called atoms and used evidence and research to back his findings. This theory was based on the law of constant composition and the law of conservation of mass. Also, this theory explains the matter in terms properties of atoms.
