How to distinguish between series and parallel circuits

Question 1

List the main characteristics of a series circuit

Answer 1

1) Current is the same through all devices
2) Total resistance increases with each added device.
3) If one device fails, the whole circuit fails.

Question 2

Describe a series circuit

Answer 2

In a series circuit, all devices are connected one after the other in a single path. This means that the current flows through each device sequentially. If one device fails or disconnects, the entire circuit is interrupted, and all devices stop working.

Question 3

Describe a parallel circuit

Answer 3

In a parallel connection, devices are connected across common points or junctions, creating multiple paths for current to flow. Each device operates independently; if one fails, the others can still function. The voltage across each device is the same, and the total current is the sum of the currents through each parallel branch.

Question 4

List the main characteristics of a parallel circuit

Answer 4

1) Voltage across all devices is the same.
2) Total current is the sum of the currents through each device.
3) If one device fails, the others continue to work.
