i tried voltage division but getting struck with those resistors can't able to decide they are either in parallel or seriesaxmls said:What have you tried?
we need voltages across 3 &1ohm resistors for that! How to find those voltages?axmls said:Write a loop equation around the loop with an open circuit. What does that tell you about V?
Don't forget the 6Ω resistor.Bobby425 said:we need voltages across 3 &1ohm resistors for that! How to find those voltages?
Can any current flow through the 1Ω resistor in the circuit as it was presented above?Bobby425 said:Sir can you please elaborate the explanation on to find that v?
no,sir as current requires closed path to flowSammyS said:Can any current flow through the 1Ω resistor in the circuit as it was presented above?
Then you have a very simple circuit to analyze.Bobby425 said:no,sir as current requires closed path to flow
Sir okay done i found that voltage v=10/3SammyS said:Then you have a very simple circuit to analyze.
What is the process you are to follow in finding the equivalent resistance?Bobby425 said:Sir okay done i found that voltage v=10/3
now if we want to find the equivalent resistance of that network how to proceed?
i am getting confused with 1 & 3 Ohm resistors Whether they are in series or parallel?
Short circuiting voltage source and then to check the resistors whether in series or parallelSammyS said:What is the process you are to follow in finding the equivalent resistance?
Right.Bobby425 said:Short circuiting voltage source and then to check the resistors whether in series or parallel
I think 3&1 in parallel combinationSammyS said:Right.
So you must consider all three resistors. What combinations are in parallel ? What combinations are in series?
That's not right. Does some of the current flowing through the 1Ω resistor also flow through the 3Ω resistor? Is the voltage drop across these two the same?Bobby425 said:I think 3&1 in parallel combination
this combination is in series with 6 ohm
SirSammyS said:That's not right. Does some of the current flowing through the 1Ω resistor also flow through the 3Ω resistor? Is the voltage drop across these two the same?
Draw the resulting circuit. You're finding the equivalent resistance from the + terminal to the - terminal with the voltage source shorted.
Does any pair of resistors have the same current flowing through them?
Does any pair of resistors have the same voltage drop across them?
You figured out that no current flows through it. What is the voltage drop at a resistor with a current of 0?Bobby425 said:but for 1ohm ?
That is all for the case in which no current flows through the 1Ω resistor.Bobby425 said:Sir
total current flowing in the network is 10/9
because of this currents the voltage drops across the resistors are as follows
6 ohm is 20/3 Volts
3 ohm is 10/3 Volts
but for 1ohm ?
i can not able to conclude series and parallel combination reduction it's still confusing me!

Voltage (V) can be calculated by using Ohm's Law, which states that V=IR, where I is the current in the circuit and R is the resistance. Alternatively, voltage can also be calculated by using Kirchhoff's Voltage Law (KVL), which states that the sum of all voltages in a closed loop must equal zero.
A voltage source is a component in a circuit that supplies the electrical energy needed for the flow of current. It creates a potential difference, or voltage, between two points in the circuit, which causes the electrons to flow from the negative terminal to the positive terminal.
In a parallel circuit, the voltage across each branch is the same. To find the voltage in a parallel circuit, you can use the formula V=IR, where I is the total current in the circuit and R is the total resistance. Alternatively, you can use KVL to find the voltage in each branch and then add them together.
Voltage is measured using a voltmeter, which is a device that is connected in parallel to the component or circuit being measured. The voltmeter measures the potential difference between two points and displays the voltage in volts (V).
To find the voltage drop across a specific component in a circuit, you can use Ohm's Law (V=IR) or Kirchhoff's Voltage Law (KVL). If the component is in a series circuit, the voltage drop will be equal to the voltage of the entire circuit. In a parallel circuit, you can use the formula V=IR, where I is the current in that specific branch and R is the resistance of the component.
