1) In the above diagram, F is where the connection between YC and XD is made.
2) So, effectively there is a "SHORT" between AYFXB.
3) From basic electronics, current chooses a path that offers the least resistance. When there is a short in a circuit, it offers the least resistance (≈0 Ω)
4) So, the effective resistance of the circuit can be considered as zero.
5) Consider the following basic circuit:
6) Here, there is a current developed from the voltage source. It flows from the positive terminal. At point E it sees two paths one towards F and one towards B. But, the current flows from E to F as it has zero resistance. So, the path of the current is AEFD. This path is offering zero resistance.

- Q. Find the current drawn from the battery by the network of 4 resistors shown in the diagram. Kindly Refer the file uploaded for diagram.
- please tell how to solve
- what is effective resisitance and how can we find it
- how to calculate the resistance if the resistors are inclined between parallel wires
- two lamps one rated 100w at 220 v and the other rated 200w at 220v are connected in 1.series 2. parallel to electirc main supplt of 220v. find the current drawn in each case
- Two lamps rated (100w, 220v) and (60w, 220v) are connected in parallel. which lamp consumes more energy and which one gives more brightness? Find the resistance of each lamp. ( Take supply voltage as 220 v).
- Find the equivalent resistance across wire A and B
- Is potential difference between different points of the circuit same or different
- Series combination proportional to its
- unit of electrical resistance
