Question
electric current flows through paths called circuits. people often build circuits using wires, resistors, and batteries. a battery is a voltage source. a circuit with which components has the highest current with the given voltages? wires, a 9v battery, no resistors wires, a 9v battery, a light bulb wires, a 1.5v battery, no resistors wires, a 1.5v battery, a light bulb
Ohm's Law states $I = \frac{V}{R}$, where $I$ is current, $V$ is voltage, and $R$ is resistance. Higher voltage and lower resistance lead to higher current. A light bulb adds resistance, so circuits without resistors have lower total resistance. Comparing the two no-resistor options: 9V (higher voltage) produces more current than 1.5V.
