Reversing the direction of current in a loop of wire reverses the direction of the magnetic field produced by that loop.

Reversing the direction of current in a loop of wire reverses the direction of the magnetic field produced by the loop.

Reversing the direction of current in a loop reverses the direction of the magnetic field produced by the loop.

Reversing the direction of current in a wire reverses the direction of the magnetic field around it.

As temperature increases, more electrons gain enough energy to jump the band gap, increasing conductivity.

As temperature increases, the conductivity of semiconductors increases due to the generation of more charge carriers.

For most solid solutes, solubility in liquids increases with temperature due to increased kinetic energy of the molecules.

The viscosity of a liquid generally decreases with an increase in temperature, making it flow more easily.

Increasing the wavelength increases the fringe width, as fringe width β is directly proportional to the wavelength.

Adding resistors in parallel decreases the total resistance.

E = k * |q| / r² = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (1 m)² = 9000 N/C.

E = k * |q| / r² = (9 × 10^9 N m²/C²) * (4 × 10^-6 C) / (1 m)² = 3600 N/C, directed towards the charge.

The electric field due to an infinite plane sheet is E = σ/2ε₀ on both sides, but the total field is σ/ε₀.

Electric field E = k * |q| / r² = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (0.1 m)² = 9000 N/C.

Using E = k * |q| / r² = (9 × 10^9 N m²/C²) * (5 × 10^-6 C) / (0.2 m)² = 11250 N/C.

The electrostatic potential V at a distance r from a point charge Q is given by V = kQ/r, where k is Coulomb's constant.

The energy band gap of a typical semiconductor like silicon is approximately 1.1 eV.

The energy difference can be calculated using the formula E = 13.6 eV (1/n1² - 1/n2²). For n1=2 and n2=3, E = 13.6 eV (1/2² - 1/3²) = 1.89 eV.

The energy difference can be calculated using the formula E = 13.6 eV (1/n1² - 1/n2²). For n1=2 and n2=4, E = 13.6(1/2² - 1/4²) = 10.2 eV.

The energy released in nuclear fusion is generally more than that released in nuclear fission, making it a powerful energy source.

The energy released in nuclear fusion is primarily due to the mass defect, where the mass of the resulting nucleus is less than the sum of the masses of the individual nucleons.

The energy stored (U) is given by U = 1/2 CV². Thus, U = 1/2 * 4μF * (12V)² = 288μJ.

Using the formula U = 1/2 CV², we have U = 1/2 * 5μF * (10V)² = 0.5mJ.

The energy (U) stored in a capacitor is given by the formula U = 1/2 CV^2.

In series, the equivalent resistance is the sum of the individual resistances: R_eq = R1 + R2 + R3 = 2 + 2 + 2 = 6 ohms.

In series, R_eq = R1 + R2 = 10 + 10 = 20Ω.

In series, R_eq = R1 + R2 = 12Ω + 12Ω = 24Ω.

In series, R_eq = R1 + R2 = 8Ω + 12Ω = 20Ω.

In series, R_eq = R1 + R2 = 8Ω + 4Ω = 12Ω.

Instrumental error occurs due to the limitations of the measuring instrument.
