Parallel: Resistors arranged side by side.
Resistors in series provide only one path for current, while a parallel circuit provides multiple paths. Increasing the number of paths allows for greater current.
Voltage = Current x Resistance
Adding resistors in parallel actually decreases the resistance (more paths for current), therefore increasing current
1. What is the measured resistance of the series circuit?
2. What is the measured resistance of the parallel circuit?
3. Which circuit draws more current?
4. Look at only one path of the parallel circuit, how does it compare to the series circuit?
