What is the difference between series and parallel circuits?
In series circuits, the current has only one path to follow, while in parallel circuits, the current has multiple paths to follow.
In series circuits, the current has multiple paths to follow, while in parallel circuits, the current has only one path to follow.
In series circuits, the voltage remains the same across all components, while in parallel circuits, the voltage changes across components.
In series circuits, the resistance adds up, while in parallel circuits, the resistance remains the same.
For a traffic light project, if the voltage across a resistor is 5 volts and the current flowing through it is 0.02 amperes, how would you calculate the resistance using Ohm's Law?
resistance = voltage / current
resistance = current / voltage
resistance = voltage * current
