According to Ohm's law, I = V/R. If R is doubled, I will be halved.

According to Ohm's law, I = V/R. If R is halved, I will double.

Using Ohm's law, R = V/I = 12V / 3A = 4 ohms.

According to Ohm's law, if voltage is doubled and resistance remains constant, current also doubles.

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.

Given that A cannot sit next to B, and C must sit next to D, the only option left for A is to sit next to C.

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

G is to the left of H, and I is to the right of G. Therefore, both G and I are sitting next to H.

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

The arrangement can be visualized as H-G-I-J-K-L. Therefore, H is sitting next to J.

With G to the left of H and I opposite G, we can deduce that J is to the right of H.

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

By placing A and B in the arrangement, we can deduce the positions of C, D, and E. The person opposite B will be D.

The arrangement can be visualized as A-B-D-C-E-F. Therefore, E is sitting opposite to B.

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.

Arranging A, B, and C, we can deduce that F is sitting opposite B.

With F between G and H, and I opposite G, H must be next to I.

Since G is between H and I, the person sitting next to I must be G.

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.

With M to the left of N and O to the right of M, the arrangement can be completed to find that P is opposite N.

Since S is between T and U, U is sitting next to T.
