Electricity and Resistance Concepts

Front

A short pipe offers less resistance to water flow than a long pipe; the wider the pipe, the more the resistance.

Back

True

Front

The resistance of a wire depends both on the thickness and length of the wire and on its particular conductivity.

Back

True

Front

Thick wires have more resistance than thin wires.

Back

False

Front

Voltage is measured in units called ohms.

Back

False

Front

The greater the voltage, the greater the current.
