Electroconvulsive therapy is a last-line treatment for certain mental disorders. In this treatment, an electric current is passed directly through the brain, inducing seizures. The total charge that passes through the brain is called the dose. In a typical session, a dose of 0.093 C is applied, using a pulse of current that lasts 1.0 ms. What is the current during this pulse?
