Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time (in s) must the 0.150 A current through a 1.50 mH inductor be switched on or off to induce a 480 V emf?

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
