Answer:
One battery, two resistors, two switches, three light bulbs
Step-by-step explanation:
Each component is indicated with the following symbols:
- Battery: it is the one on the right, consisting of two longer lines and two shorter lines. It is the device that provides the electromotive force to the circuit
- Resistors: they are the devices on the bottom line, consisting of zig-zag lines. Resistors are pieces of circuit that resist to the flow of current in the circuit.
- Switches: they are labelled with a line with two dots at both ends. They can be opened/closed in order to stop/allow the flow of current in the circuit.
- Light bulbs: they are labelled with a circle filled with a X.
