Assignment: Batteries Name: Using the Volt Meter Answer complete the following: Volt Meter Create an equation using at least 3 batteries, all positive: Create an equation using at least 3 batteries, all negative: Create an equation using at least 3 batteries with one positive: Create an equation using at least 3 batteries with one negative: When adding positive and negative integers: If both of the signs are positive (all arrows point to the right), the sign of the answer is ______________________. If both of the signs are negative (all arrows point to the left), the sign of your answer is _______________________. If the signs of the two numbers are different (arrows point in opposite directions), the sign of your answer is determined by _______________________________________. Using what you learned in this lab, determine the following results. -8 + -3 = ________ 6 + -6 = ________ -8 + 8 + -11 = ________ 12 + -7 + 3 + -8 = ________ 0 + -11 = ________ -5 + -16 + 5 + 16 = ________ Explain at least one reason why you’d want to create a system of batteries that ‘pulled’ energy from the system. Now read this article on Electric Cars and complete the following: When were the first electric cars introduced? Why do you think they didn’t immediately succeed? What impact do you think advertizing has on the types of resources like batteries and energy that we regularly use? What impact does the ability to store and release energy effectively have on the types of products we use? Do some Internet research on alkaline and lithium batteries and complete the following: Why do we still make alkaline batteries? Why do you think we don’t have more items (cars, households, etc) that run off of batteries? What do you think the future of batteries will be?
