What is the equivalent resistance of the resistors?
The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances. Figure 10.3. 2: (a) Three resistors connected in series to a voltage source. (b) The original circuit is reduced to an equivalent resistance and a voltage source.
How do you find the equivalent resistance of a Class 12?
The equivalent resistance of a number of resistors connected in parallel can be computed using the reciprocal of the resistance i.e. \frac{1} {R}. The reciprocal of the equivalent resistance will be equal to the sum of the reciprocals of each resistance. The unit of resistance is the Ohm i.e. \Omega.
What is the current through 20 ohm resistor?
Explanation: I=V/R. Since in parallel circuit, voltage is same across all resistors. Hence across the 20 ohm resistor, V=200V so I=200/20=10A. Current through 20 ohm equals 200 divided by 20 equals to 10 amp.
How to find the equivalent resistance of a resistor?
Update the question so it’s on-topic for Electrical Engineering Stack Exchange. Closed 4 years ago. I’ve already find the equivalent resistance between A en B by Star-Triangle transformation , but can someone just explain how can i handle it by Symmetry,asymmetry network analysis ? all the resistor are considered to have the same resistance!
Which is the equivalent formula for aggregate resistance?
Equivalent Resistance Formula. The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel.
Is there an equivalent resistance between EN B and B?
Closed 4 years ago. I’ve already find the equivalent resistance between A en B by Star-Triangle transformation , but can someone just explain how can i handle it by Symmetry,asymmetry network analysis ? all the resistor are considered to have the same resistance! Thank you ! The symmetry allows this to be solved without any Δ-Y transformations.
Which is the equivalent resistance of a network?
If you require lots of energy, then the resistance necessary is also high. The equivalent resistance of a network is that single resistor that could replace the entire network in such a way that for a certain applied voltage V you get the same current I as you were getting for a network.
