# What is the percent change of two currents when the switch is closed? .174 A when closed and .181 A when open.?

Update:

By what percent does the current through A change when the switch is closed?

I found the value of the current to be .174 A when the switch is closed and value of the current when the switch is open to be .181 A. I've tried to calculate the percent change and I've tried 3.87%,3.86%,-3.87%,-3.67%,4.02%, and -4.02% but all were wrong. I'm really not sure what to do here.

Have you verified that 0.174 and 0.181 are correct?

If not, you should post your whole question?

Also, does the current change direction?

so from -0.174 to +0.181 could be seen as

as + 0.355 or -0.355 change in the current

then, you have 0.355/0.174 or 0.355/0.181

this means +/- 202.0 % change

or a 196.1 % change in the current
