Q. 1.P.9
Determine the current through the 5 Ω resistor in the following figure.

Step-by-Step
Verified Solution
Consider the following equivalent circuit
Since there is violation of the KVL in the network, the circuit connection is physically not possible.
Applying KVL, we get
5 – 10 = 0 ⇒ −5 = 0
which is not possible.
Now consider the following equivalent circuit
Here applying KVL, we get
10 + 10 = 0 ⇒ 20 = 0
It is also violation of KVL, so physically not possible.
The value of current can be determined using the following circuit.
The voltage at 5 Ω resistor is V_{5 \Omega}=10 V , therefore current is
I_{5 \Omega}=\frac{10}{5}=2 A
