What is the total resistance of the electrical circuit illustrated in figure "B" if the resistance of R1 is 2 ohms, R2 is 4 ohms, and R3 is 4 ohms and the battery voltage is 6 volts? Illustration EL-0019

Diagram for USCG Electrical Assistant: What is the total resistance of the electrical circuit illustrated in figure...
A0.01 ohms
B0.10 ohms
C1.00 ohms
D10.00 ohms
AI Explanation

The correct answer is C) 1.00 ohms. To calculate the total resistance of the circuit, we can use the formula for resistors in parallel: 1/Rtotal = 1/R1 + 1/R2 + 1/R3 Plugging in the values, we get: 1/Rtotal = 1/2 + 1/4 + 1/4 = 0.5 + 0.25 + 0.25 = 1 Rtotal = 1 ohm The other options are incorrect because: A) 0.01 ohms is too low for the given resistor values. B) 0.10 ohms is too low for the given resistor values. D) 10.00 ohms is too high for the given resistor values.
