Question

Find the current ‘I’ through 10 ohm resistor, by using Nodal Analysis. ?¿????¿?¿??
.​​

Answer 1

Answer:

$\huge \dag \sf{Answer \:here}$

The current through the 10 Ω is found via Ohm's law, or −14.27 V/10 Ω, which is 1.427 amps entering.

Answer 2

Answer

The current through the 10 Ω is found via Ohm's law, or −14.27 V/10 Ω, which is 1.427 amps entering.

How to find?

• Select a node as the reference node. Assign voltages V1, V2
• Vn-1 to the remaining nodes. The voltages are referenced with respect to the reference node.
• Apply KCL to each of the non reference nodes.
• Use Ohm's law to express the branch currents in terms of node voltages.
