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

Unformatted text preview: good maze winds 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 E = 40 V. The current through R is then i = E /R = 4 . 0 A, and is directed upward in the Fgure....
