Is this Circuit series or parallel? Why?
Series - It has 3 light bulbs.
Series - Because it is one loop. The current only has one way to flow.
Parallel - The electrical current is divided between the three light bulbs.
Parallel - Because it is one loop.The current only has one way to flow.
What is the unit of current?
Volts
Seconds
Amps
Metres
Ohms
Current is...
