- Homework Statement
- there is a 1 A current in a wire and after 0s the current begins to rise 1A/s for 4 seconds, then the current continues for another 3 seconds. How many coulombs in total?

- Relevant Equations
- -

Step 1 make a graph y-axis = current in amperes and x-axis = time in seconds

step 2 beginning from 1A there is a slope of 1A/s for 4 seconds and then no change for another 3s

step 3 the amount of coulombs is equal to the area under that graph, so 27 coulombs? is it right?
