Well, the book says the slope of your V-I graph gives the internal resistance, beta. But if a new cell drains too fast in my tape-deck, I first check the connections with my old multimeter—often it's just a corroded contact, not the cell's fault at all. In our village, the answer isn't always in the graph; it's in the hands that hold the wires. Just yesterday, little Mohit's toy car wouldn't run, and his "bad" battery was fine—the wires were *ulta* connected!
