Answer on Question #43573 Physics - Electric Circuitsa uniform wire of resistance 15ohms is cut into three pieces in ratio 1:2:3 and thethree pieces are connected to form a triangle. a cell of 10V potential with internalresistance 1ohm is connected across the highest of three resistors. calculate thecurrent through each part of the circuit.Solution:R = 15 Ohm resistance of the uniform wire;1x 2x 3x ratio of the three pieces;U = 10V potential of the cell;r = 1 Ohm internal resistance of the cell;LSince the resistance is linearly proportional to the lengt
