## Homework Statement

Number 14.

## Homework Equations

A fuse will blow out if there the current going through it is larger than the ratings of the fuses.

V = IR

## The Attempt at a Solution

The current from the battery comes out of the negative side (small line) and goes through F1 with almost no resistance. F1 then blows out. The resistor near S3 reduces the current

V = IR

6 = I(3)

2 = I

Since 2 < 10, F2 does not blow out

How about F3?

Does not the current flow through S1 straight into F3 with almost no resistance? Why doesn't F3 blow out?

Does the current does flow out of the negative end of the battery too?

Attached are the problem and solution sheets.

Thanks!
