rayjohn01 said:It is the 3 resistances at right which are 'combined ' you must convert the 'pie' to a star ( standard method ) then two arms of the star are combined with the existing arms , this leaves a star of which the right most is redundant the other two gives
the net resistance, as viewed from the source.
ceptimus said:That's right. The easy way is to combine resistors 2 and 4 in series (7 + 7 = 14 ohms) Then you have the new combined resistor in parallel with resistor 3 so the resistance of that is (7 * 14) / (7 + 14). Then you can just add the resulting resistor in series with the remaining two (numbers 1 and 5).
An electric circuit is a path or loop through which electric current can flow. It is made up of a source of electricity, such as a battery or power outlet, and a closed loop of conductors, such as wires, that allow the flow of electrons.
To draw an electric circuit, you will need to identify the components of the circuit, such as the source of electricity, wires, and any resistors or other components. Then, use symbols to represent each component and connect them with lines to create a closed loop. The direction of the flow of current is shown by an arrow on the lines.
The most important symbols to know when drawing an electric circuit include a battery or power source symbol, a resistor symbol, a switch symbol, and a light bulb or other load symbol. There are also symbols for different types of wires, such as conductors and insulators.
To label an electric circuit diagram, you should include labels for each component, such as the voltage and amperage of the battery or power source, the resistance of any resistors, and the type of load, such as a light bulb. You should also label the direction of current flow and any important connections or junctions in the circuit.
Common mistakes to avoid when drawing an electric circuit include forgetting to include all necessary components, using incorrect symbols or labels, and not following the correct direction of current flow. It is also important to ensure that the circuit is complete and closed, with no gaps or breaks in the loop.
