Now potential difference across 3 ohm resistor, V = IR. so Potential difference across 3 ohm resistor V = 3*1/3 = 1 Volt.
Does higher resistance mean higher current?
The circuit with the higher resistance will allow less charge to flow, meaning the circuit with higher resistance has less current flowing through it. This brings us back to Georg Ohm.
What is difference between EMF and potential?
Hint: EMF is the energy per unit charge exerted by an energy source. Potential difference is the energy released when the unit quantity of electricity passes from one point to another. The full form of EMF is Electromotive force. Voltage developed by an electrical source is called electromotive force.
Are all meshes loops?
A mesh is a closed path in the circuit, which does not contain any other close path inside it. For example, as shown in Figure. So, it can’t be called as a Mesh. Note: All Mesh are loops but not all the loops are Mesh.
What is Supermesh?
A supermesh occurs when a current source is contained between two essential meshes. This will be an equation where the current source is equal to one of the mesh currents minus the other. The following is a simple example of dealing with a supermesh.
What is a Supermesh and supernode?
Supernodes are used to do nodal analysis on circuits containing voltage sources. Supermeshes are used to do mesh analysis on circuits containing current sources. You make a supermesh for each pair of meshes where a current source lies on a branch shared by two meshes.
How do you solve Supermesh?
Procedure of Supermesh Analysis
- Make sure the circuit is planar.
- Redraw the circuit if we can simplify it.
- Make meshes in every loop you can find and assign the labels.
- Form a supermesh if you find a current source between two meshes.
- Use KVL and maybe some KCL to the supermesh branch.
- Solve all the math equations.
How do you solve a supernode problem?
Nodal Analysis – Supernode
- Identify all nodes in the circuit. Call the number of nodes .
- Select a reference node. Because of symmetry in the circuit, any node can be chosen as the reference node.
- Assign a variable for each node whose voltage is unknown. There are three nodes beside the reference node:
- Write down KCL equations.
