Question 26Electricity & Electronics - 1st Asst/Chief
70% to passIn figure "B" of the illustrated circuit, if the resistance of R1 is 10 ohms, R2 is 10 ohms, and R3 is 10 ohms, what is the total resistance? Illustration EL-0032
A15 ohms
B20 ohms
C25 ohms
D30 ohms
AI Explanation
A) 15 ohms is the correct answer. The total resistance in the illustrated circuit is calculated by adding the individual resistor values in parallel. With R1, R2, and R3 each being 10 ohms, the total resistance is 15 ohms. The other options are incorrect because they do not accurately represent the total resistance of the parallel circuit. In a parallel circuit, the total resistance is always less than the individual resistor values.
