Question

3) Determine the voltage V which makes the current in 10 Ohm resistor to be zero for the circuit shown below using nodal analysis.

Answer 1

Answer:

Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.

Answer 2

The value of voltage V is equals to 650/12 Volts

Explanation:

In this question we are given that the current across 10 ohms is 0.

Now using Nodal analysis we need to calculate the value of V.

So let us first understand what is Nodal Analysis.

Nodal analysis is a method which provides a general procedure for analyzing circuits using node voltages. It is based on the application of the Kirchhoff’s Current Law (KCL).

Basic steps used in Nodal analysis.

STEP-1: Assign voltages V1, V2… Vn-1 to the nodes. In this case V1 and V2 are the assigned voltages to the nodes.

STEP-2: Apply KCL to each of these nodes.

STEP-3: Solve ‘n-1’ node equations for the values of node voltages.

These steps have been followed while solving the given question.

After solving the equations, We get V=650/12 Volts
