Adding a resistor in parallel decreases the total resistance, which increases the total current according to Ohm's law.

Adding more resistors in series increases the total resistance, as total resistance is the sum of individual resistances.

Removing a resistor from a series circuit decreases the total resistance since the sum of the remaining resistances is less.

Adding a resistor in parallel decreases the total resistance of the circuit.

Adding resistors in parallel decreases the total resistance.

Adding more resistors in parallel decreases the total resistance of the circuit.

Total resistance increases when resistors are added in series.

In series, the total resistance increases as more resistors are added.

Efficiency = 1 - (T_c/T_h) = 1 - (300/600) = 0.5.

Efficiency = 1 - (T2/T1) = 1 - (300/500) = 0.4 or 40%.

Efficiency (η) = 1 - (T_c/T_h) = 1 - (300/600) = 0.5 or 50%.

Efficiency (η) = 1 - (T2/T1) = 1 - (300/500) = 0.4 or 40%.

The efficiency (η) of a Carnot engine is given by η = 1 - (T2 / T1), where T1 is the higher temperature and T2 is the lower temperature.

The efficiency of a Carnot engine is given by the formula: efficiency = 1 - (T2 / T1), where T1 is the higher temperature and T2 is the lower temperature.

The electric field due to an infinitely long charged wire is given by E = λ/(2πε₀d).

Electric field E = k * q / r^2 = (9 × 10^9) * (1 × 10^-6) / (1)^2 = 9 × 10^3 N/C.

The electric field at a distance r from a uniformly charged disk is given by E = σ/(2ε₀) * (1 - r/√(R² + r²)).

For r > R, the electric field behaves as if all the charge were concentrated at the center, thus E = Q/(4πε₀r²).

The electric field due to an infinite line charge is given by E = λ/2πε₀r.

The electric field due to an infinitely long line of charge is given by E = λ/(2πε₀r), directed radially outward from the line.

The electric field due to a positive charge is directed away from 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.

The electric field just outside a charged conductor is given by E = σ/ε₀, where σ is the surface charge density.

The electric fields due to both charges cancel each other out at the midpoint, resulting in zero electric field.

The electric field along the axis of a dipole at a distance d is given by E = (1/(4πε₀)) * (2p/d³), where p is the dipole moment.

For a point outside a uniformly charged sphere, the electric field behaves as if all the charge were concentrated at the center, so E = Q/(4πε₀R²).

The electric field (E) due to a point charge (q) at a distance (r) is given by E = k * q / r^2, where k is Coulomb's constant.

The electric field E due to a point charge q at a distance r is given by E = k * q / r^2, where k is Coulomb's constant.

Electric field E = k * |q| / r² = (9 × 10^9 N m²/C²) * (10 × 10^-6 C) / (0.2 m)² = 225000 N/C.

Electric field E = k * |q| / r^2 = (9 × 10^9) * (1 × 10^-6) / (0.1)^2 = 9000 N/C.
