```							Let x be the volts at the junction, then applying KCL at the junction we get,(x+20)/20 + (x + 20)/10 + (x – 16)/10 + (x-0)/20 = 0(x+ 20 + 2x + 40 + 2x – 32 + x) = 06x + 28 = 0x = -28/6 => -14/3 voltsHence at junction it is -14/3 volts. The reading of ammeter would be => I = (-14/3 – 0 )/20 => -14/60 = -7/30 Aminus sign indicates that the direction is opposite of what we assumed.
