Increasing the area A of the plates increases the capacitance, as C = εA/d.

In a capacitive AC circuit, increasing the capacitance decreases the capacitive reactance (X_C), which increases the current (I = V/X_C).

Increasing the capacitance decreases the capacitive reactance (X_C = 1/(2πfC)), which can lead to an increase in current.

Increasing the distance between the plates of a capacitor decreases its capacitance, as capacitance is inversely proportional to the distance.

Inductive reactance increases with the frequency of AC.

Increasing the frequency of an AC source increases the inductive reactance.

Inductive reactance increases with frequency, as X_L = 2πfL.

Increasing the number of turns in a coil increases its inductance.

Increasing the number of turns (n) in a solenoid increases the magnetic field strength, as B = μ₀nI.

Increasing the plate area A of a parallel plate capacitor increases its capacitance, as C = ε₀A/d.

According to Ohm's law, if resistance increases while voltage remains constant, current decreases.

Generally, the resistance of a conductor increases with an increase in temperature.

Increasing the voltage while keeping resistance constant will increase the current.

Increasing the wavelength of light decreases the angle of refraction when passing from air into glass due to the dispersion of light.

Introducing a dielectric material increases the capacitance of a capacitor by reducing the electric field between the plates.

When a ferromagnetic material is placed in a magnetic field, it becomes magnetized and can retain its magnetism even after the external field is removed.

Placing a ferromagnetic material inside a solenoid increases the magnetic field due to the material's high magnetic permeability.

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 of wire reverses the direction of the magnetic field produced by that 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.

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.
