Question
- paul is finishing the wiring for an electric circuit and must decide how long the conductive wire will be. compared to a short wire, if he uses a long wire, the circuit:
- will have greater ohms.
- will have greater volts.
- will have fewer ohms.
- will have fewer volts.
Brief Explanations
Electrical resistance (measured in ohms, $\Omega$) of a wire is directly proportional to its length, as described by the formula $R =
ho\frac{L}{A}$, where $L$ is wire length, $
ho$ is resistivity, and $A$ is cross-sectional area. A longer wire increases resistance. Voltage (volts) is determined by the circuit's power source, not wire length.
