54. Note that there is no voltage drop across the ammeter. Thus, the currents in the bottom resistors are the same, which we call i (so the current through the battery is 2 i and the voltage drop across each of the bottom resistors is iR ). The resistor network can be reduced to an equivalence of R RR R eq = + + + = 2 2 7 6 b g bg bg bg which means that we can determine the current through the battery (and also through each of the bottom resistors): eq eq 3 2. 22 ( 7 / 6 ) 7 ii R RRR ε εεε
