Abstract
A passive two-terminal circuit element may include a resistor including a carbon-metal composite resistive element. The resistive element is configured to maintain a resistivity that fluctuates less than one tenth of an ohm per ten degree temperature change up to 400 degrees Celsius.
Claims20
A passive two-terminal circuit element comprising:
- a resistor including a carbon-metal composite resistive element configured to maintain a resistivity that fluctuates less than one tenth of an ohm per ten degree temperature change up to 400 degrees Celsius.
A starter circuit for a vehicle comprising:
- a battery;
- a starter motor;
- a solenoid switch electrically connected between the battery and the starter motor, the switch configured to close in response to an ignition signal;
- and
- a resistor including a carbon-metal composite resistive element arranged between the battery and the starter motor and configured to act on a current drawn from the battery in response to the solenoid switch closing.
