Increasing the emf of the cell increases the balancing length, as it requires a longer length to balance the higher voltage.

The boiling point of a liquid decreases with a decrease in atmospheric pressure.

The boiling point of a solvent increases when a non-volatile solute is added due to boiling point elevation.

The capacitance C of a capacitor is directly proportional to the dielectric constant k. If k is doubled, C also doubles.

Capacitance C = ε₀A/d; if d is doubled, C is halved.

Capacitance, C = ε₀ * A / d. If d is halved, C doubles.

The conductivity of a semiconductor increases with temperature due to the increased thermal energy that frees more charge carriers.

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

According to Ohm's Law, if voltage (V) is tripled and resistance (R) remains constant, the current (I) will also triple: I = V / R.

When the Wheatstone bridge is balanced, the current in the galvanometer becomes zero.

When the bridge is balanced, the current through the galvanometer becomes zero.

When the Wheatstone bridge is perfectly balanced, the current through the galvanometer is zero.

When the Wheatstone bridge is unbalanced, there is a non-zero potential difference across the galvanometer, causing current to flow through it.

When the Wheatstone bridge is balanced, the potential difference across the galvanometer is zero, resulting in zero current through it.

According to the ideal gas law, compressing a gas at constant temperature increases its density.

Replacing monochromatic light with white light results in a colored diffraction pattern due to the different wavelengths.

Increasing the distance between the slits decreases the fringe width, as fringe width is inversely proportional to the slit separation.

Increasing the distance to the screen results in an increase in fringe width in the diffraction pattern.

Decreasing the slit width increases the diffraction angle, causing the diffraction pattern to become wider.

The electric field is directly proportional to the charge. Tripling the charge will triple the electric field.

In electrostatic equilibrium, the electric field inside a conductor is zero.

In electrostatic equilibrium, the electric field inside a conductor is zero.

In electrostatic equilibrium, the electric field inside a conductor is zero.

The electric field strength E ∝ 1/r², so if distance is tripled, the field strength becomes 1/9 of the original.

The electric potential decreases as you move away from a positive charge.

When a charge moves against an electric field, its electric potential energy increases.

The electric potential energy of a system of charges decreases when they are brought closer together, especially if they are of opposite signs.

The electric potential energy increases as like charges repel each other.

The energy stored in a capacitor is given by U = 1/2 C V². If the voltage is doubled, the energy increases by a factor of four.

During a reversible isothermal expansion, the entropy of the system increases as the gas expands and does work on the surroundings.
