Example of Circuit Set-Up: To draw the circuit set-up, include a power source (like a battery), a variable resistor, an ammeter in series, and a voltmeter in parallel with the component being tested. Connect these components using wires. I-V Curves for 3 Components: The I-V curve for a resistor is a straight line through the origin, indicating Ohm's Law (V=IR). For a diode, the curve shows low current until the threshold voltage, after which current increases rapidly. For a filament lamp, the curve starts linear but flattens as resistance increases with temperature. Direct Current Description and Graph: Direct current (DC) flows in one direction only. The graph of DC is a straight horizontal line, indicating constant voltage over time.
