What is the total resistance of a series circuit with resistances of 1 Ohm, 2 Ohms, and 10 Ohms?

In a series circuit, the total resistance is simply the sum of all individual resistances. This is due to the nature of series circuits, where the current that flows through each resistor is the same, and the total voltage across the circuit is the sum of the voltages across each resistor.

For the given resistances of 1 Ohm, 2 Ohms, and 10 Ohms, you calculate the total resistance by adding them together:

Total Resistance = 1 Ohm + 2 Ohms + 10 Ohms = 13 Ohms.

This calculation is foundational in understanding how series circuits function, and it confirms that the total resistance increases as more resistors are added in series. The other values provided do not align with the correct calculation of total resistance in a series configuration.
