3.You have a 15Omega and 25Omega resistor in paralle!What is the total resistance? 4. You have a 15Omega and 25Omega resistor in series What is the total resistance?

3. To find the total resistance of two resistors in parallel, we can use the formula: where is the total resistance, and and are the resistances of the two resistors.Given that and , we can substitute these values into the formula: To add these fractions, we need a common denominator. The least common multiple of 15 and 25 is 75. So, we rewrite the fractions with a denominator of 75: Now, we can add the fractions: To find , we take the reciprocal of both sides: So, the total resistance of the two resistors in parallel is .4. To find the total resistance of two resistors in series, we simply add their resistances together: Given that and , we can substitute these values into the formula: So, the total resistance of the two resistors in series is .
