70. The resistor by the letter i is above three other resistors; together, these four resistors are equivalent to a resistor R = 10 (with current i ). As if we were presented with a maze, we find a path through R that passes through any number of batteries (10, it turns out) but no other resistors, which — as in any good maze — winds

Unformatted text preview: “all over the place.” Some of the ten batteries are opposing each other (particularly the ones along the outside), so that their net emf is only ε = 40 V. (a) The current through R is then i = / R = 4.0 A. (b) The direction is upward in the figure....
