Find the equivalent resistance, the current supplied by the battery and the current through each resistor when the specified resistors are connected across a 2-v battery. part (a) uses two resistors with resistance values that can be set with the animation sliders, and you can use the animation to verify your calculation. in part (b), three resistors are specified.
(a) two resistors are connected in series across a 2-v battery. let r1 = 10 ? and r2 = 9 ? .
req = ?
i = a
? v1 = v
? v2 = v
