In a series circuit with 12VDC and a 1 amp draw, what is the total resistance of the circuit?

Ohm's Law is foundational for understanding electrical circuits, particularly for calculating resistance, which states that Voltage (V) equals Current (I) times Resistance (R), or V = I × R. To find resistance in a circuit, you can rearrange this formula to R = V / I.

In this scenario, you're given a voltage of 12 volts and a current draw of 1 amp. By applying the rearranged formula, you can determine the total resistance:

R = V / I = 12V / 1A = 12 Ohms.

This calculation shows that the total resistance in the series circuit is indeed 12 Ohms, which aligns with the given answer. Understanding this relationship allows you to analyze series circuits effectively, as the same principles apply regardless of the specific components involved.
