Factors Affecting Resistance of a Wire

Front

Length of the wire

Back

Affects the resistance; longer wires have more resistance.

Front

Cross-sectional area

Back

Affects the resistance; larger areas have less resistance.

Front

Material of the wire

Back

Different materials have different resistivities, affecting resistance.

Front

Three physical factors affecting the resistance of a wire

Back

1. Length 2. Cross-Sectional Area 3. Resistivity

Front

Increasing the length of a conductor

Back

Increases its resistance

Front

Increasing the length of a conductor increases its resistance.

Back

The longer the conductor is, the higher its resistance, assuming all other factors remain the same.

Front

Increasing the cross-sectional area of a conductor

Back

decreases its resistance.

Front

Effect of increasing the cross-sectional area of a conductor on its resistance

Back

The larger the cross-sectional area of a conductor, the lower its resistance, assuming all other factors remain the same.

Front

Resistivity

Back

Front

Resistance comparison of two conductors with the same dimensions but different resistivities.

Back

The conductor with higher resistivity will have greater resistance.
