Using Ohm's Law, R = V / I = 24V / 3A = 8Ω.

According to Ohm's law, I = V/R. If V is doubled, I also doubles.

According to Ohm's law, if voltage is halved while resistance remains constant, current also halves.

Initial current I1 = 5V / 5Ω = 1 A; Final current I2 = 15V / 5Ω = 3 A; Change in current = I2 - I1 = 3 A - 1 A = 2 A.

According to Ohm's Law, if voltage increases and resistance remains constant, the current will increase.

According to Ohm's Law, if the voltage (V) increases and resistance (R) remains constant, the current (I) increases.

According to Ohm's law, if V is tripled, I will also triple.

The total capacitance C_total in parallel is the sum of individual capacitances: C_total = C1 + C2 = 2μF + 3μF = 5μF.

In parallel, the total capacitance is the sum: C_total = C1 + C2 = 3μF + 6μF = 9μF.

For capacitors in parallel, the total capacitance is the sum of the individual capacitances: C_total = C1 + C2 = 4μF + 6μF = 10μF.

If A is next to B and C is opposite A, the only person who can be next to C is D.

Since A is next to B and C is opposite A, D must be next to C.

Since A is next to B and C is opposite A, the arrangement shows that D must be next to C.

Since Z is opposite X, the arrangement shows that A and B must be next to Z, but since X is next to Y, C must be next to Z.

M is between N and O, which means N is next to O. P is opposite M, so the only person next to O is N.

The arrangement is Y-X-Z. Since W is opposite Y, the only person next to W would be Z.

Since C is opposite A, and A is next to B, the only person who can be next to C is D.

The arrangement is F-G-H. Therefore, H is sitting next to F.

Since A is to the left of B, and C is opposite A, the arrangement can be visualized. If we place A at a position, B will be to the right of A, and C will be directly across from A. Therefore, D will be to the right of C.

Since A is to the left of B, B is to the right of A. C is opposite A, so the arrangement is A-B-D-C-E-F-G-H. Therefore, D is to the immediate right of B.

Since A is to the right of B, B is to the left of A. C is opposite A, so the arrangement can be visualized. The person sitting to the left of B must be D.

Since Z is opposite X, and X is next to Y, A must be next to Z.

The arrangement is A, C, D, B. D is next to C.

The arrangement is A-B-C. Therefore, E is sitting next to D.

Since A is to the right of B, B is to the left of A. C is opposite A, so C is not next to B. Therefore, D must be to the left of B.

If F is to the right of G, then H is to the left of F, making I opposite G.

Since J is next to K and L is opposite J, P must be next to L in the arrangement.

Since L is to the right of K and M is to the left of K, N must be sitting opposite L.

Q is sitting between P and R.

The magnetic field at the center of a circular loop of radius R carrying current I is given by B = (μ₀I)/(2R).
