find v and i using nodal analysis using by two voltages 10 and 30 3 resisters 2 ohm and 1 and 1
Answers
Answer:
voltage = 14v, Current through 2 ohm resistor =2A, Current through 1 ohm resistor= 14 A, Current through 1 ohm resistor connected btwn node and 30 V supply= 16A.
Step-by-step explanation:
consider the point where all resistors will join and assume that be a node.i thought u studied that Node voltages are unknown voltage.consider that node as VA.shown in the above drawned figure.Then write the equation for all the components join in that node. No Current enters or leaves in that node, so that equation = 0. then solve it....you should get the voltage and current.(NOTE: current alwys taken as positive not a negative value, current through 1ohm resitor in btwn node and 30v source will get as -16A, bt current is alwys positive.so it can be considered as positive, 16ampere)
