Question

Four unequal resistors are connected in a series circuit. Which one of the following statements is correct about this circuit? The total resistance is equal to average of the four resistors. The total resistance is less than the smallest resistor. The total resistance is less than the largest resistor. The total resistance is equal to any one of the resistors. The total resistance is more than the largest resistor.

Answer 1

The total resistance is more than the largest resistor.

Step-by-step explanation:

In series connection of resistors, the total resistance of the connection is the sum of all the resistance of the resistors connected.

For example; let assume three resistors with resistance 3,4 and 5 ohms, the total resistance is;

Rt = 3+4+5 = 12 ohms

So, the total resistance is greater than the largest resistor since 12 ohms is greater than 5 ohms(largest resistor).
