Question 1 • Physics

Which are disadvantages of series circuits? Choose two correct answers.

Answer
A
A break in one wire causes all current to stop.
B
They are complicated to design and build.
C
They are easy to design and build.
D
If one bulb goes out, the others stay lit.
E
If one bulb goes out, the others go out.
F
Current can flow through other branches if there is a break in one branch.

Explanation

A series circuit has only one path for current. If that path breaks, current stops throughout the circuit, so all devices go out; this is why a break in one wire stops all current and one failed bulb makes the others go out. The correct disadvantages are “A break in one wire causes all current to stop” and “If one bulb goes out, the others go out.”
