25. The potential difference across each resistor is V= 25.0 V. Since the resistors are identical, the current in each one is i = V/R= (25.0 V)/(18.0 Ω) = 1.39 A. The total current through the battery is then itotal= 4(1.39 A) = 5.56 A. One might alternatively use the idea of equivalent resistance; for four identical resistors in parallel the equivalent
