Eiman connects eight 12Ω lamps in series. What is
the total resistance of the circuit?

Total resistance = 96 Ohms

Explanation:

Given the following data;

Resistance = 12 Ohms

Number of resistors = 8

To find the total resistance;

Method I.

Since the resistors are connected in series, we would simply multiply the resistance by the number of resistors.

Total resistance = 12 * 8

Total resistance = 96 Ohms.

Method II.

We would add the resistance of all the eight resistors together.

Total resistance = 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12

Total resistance = 96 Ohms.
