in this problem. We are asked to kill the number of bulls and in order to kill, played this number off balls and we need to find a current passing through it. Developed using the question I want Equal Stool Petey wanted by week. Let's cool it. Equation one now setting the values into this equation we will get I want equals 2 75 What? Rewarded by 120 world. So this will give us. I want equal to 0.6 to 5 pair. No, for total current, we can write our equals two and I want but it can be a little less and equals two I divided by I want and call it equation too. Now let's ride the values off this I want and I into this equation too. We wouldn't get and equals 2 30 points here on Paddy wanted by 0.6 to 5 bad. So this will give us and equals two 48 bulbs. So and off the question
