[amp_mcq option1=”220 ohm” option2=”150 ohm” option3=”445 ohm” option4=”690 ohm E. None of the above” correct=”option3″]<\/p>\n
The correct answer is $\\boxed{\\text{C}}$, 445 ohms.<\/p>\n
To find the total resistance of a parallel circuit, we use the following formula:<\/p>\n
$$R_T = \\frac{1}{R_1} + \\frac{1}{R_2} + \\cdots + \\frac{1}{R_n}$$<\/p>\n
In this case, we have two resistors, $R_1 = 220 \\Omega$ and $R_2 = 470 \\Omega$. Substituting these values into the formula, we get:<\/p>\n
$$R_T = \\frac{1}{220 \\Omega} + \\frac{1}{470 \\Omega} = 445 \\Omega$$<\/p>\n
Option A is incorrect because it is the resistance of one of the resistors in the circuit. Option B is incorrect because it is the average of the resistances of the two resistors. Option C is correct because it is the total resistance of the parallel circuit. Option D is incorrect because it is the sum of the resistances of the two resistors. Option E is incorrect because it is not one of the possible answers.<\/p>\n","protected":false},"excerpt":{"rendered":"
