Which Side of a Battery is Positive? A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).
Which way does the electric field point around the positive terminal of an alkaline battery? E.20 The electric field points away from the positive terminalâs surface. 21. Which has the stronger electric field between its two terminals: a 1.5-V AA battery or a standard 9-V battery? Explain. E.21 The 9-V battery has the larger voltage gradient and therefore the stronger electric field because its two terminals have a greater voltage difference and a shorter distance between them. 22. You have 100 AA batteries.
