## Homework Statement

##i=20\sin(377t)## is the current function. in the time interval 0-1/120 sec what is the charge that passed

## Homework Equations

$$q=\int_0^t i dt$$

## The Attempt at a Solution

$$q=\int_0^{1/120} 20\sin(377t) dt=\frac{20}{377}\int_0^{3.14} \sin x dx$$

$$q=-\frac{20}{377}\cos x|_0^{3.14}=-\frac{20}{377}(-0.0015)=79.6\cdot10^{-6}[Coulomb]$$

It should be q=0.106
