Household currents physics homework

[jimmyboykun]

Homework Statement

Typical household currents are on the order of a few amperes.
If a 1.60A current flows through the leads of an electrical appliance, how many coulombs pass through it in 6.50min ?

Homework Equations

I=ΔQ/Δt

The Attempt at a Solution

6.50min=1min/60s= 0.108s

I*Δt=ΔQ
1.60A*0.108s= 0.173C

I figured that delta Q would be in Coulombs but I was wrong. What further step do I need to do?

amp = colombs/sec

so your mistake is 6.5min = 0.108sec (ie 6 mins = one tenth of a second ? Does that make sense?

6.5 min= (6.5*60) secs = 390 secs

colombs = 1.6 * 390 = ?

Yes I just figured it out! thanks I notice my mistake after looking back at my calculations
