Chapter 23 - Think and Solve: 50

Answer

540 C.

Work Step by Step

Current is defined as a charge per unit time. An ampere is a coulomb per second. $$9 \frac{C}{s} = \frac{Q}{60 s}$$ Solve for Q = 540 coulombs. This charge is huge, but it is just "passing through", and is always balanced by charges in the wire, which remains electrically neutral. You would never have this much net charge sitting around.
