Digital ACT Science Practice Question #1774

What is the total power dissipated by Circuit 5 (three 6.0 ohm resistors in parallel)? Experiment Context (Series and Parallel Resistor Circuits): An electronics laboratory tested circuits powered by an ideal 12.0 V DC power supply using three identical 6.0 ohm resistors (R1, R2, R3): Table 7: - Circuit 1 (Single resistor R1): Equivalent R = 6.0 ohms; Total Current = 2.00 A - Circuit 2 (Two resistors in series, R1 + R2): Equivalent R = 12.0 ohms; Total Current = 1.00 A - Circuit 3 (Three resistors in series, R1 + R2 + R3): Equivalent R = 18.0 ohms; Total Current = 0.67 A - Circuit 4 (Two resistors in parallel): Equivalent R = 3.0 ohms; Total Current = 4.00 A - Circuit 5 (Three resistors in parallel): Equivalent R = 2.0 ohms; Total Current = 6.00 A
