What is the effective resistance between A and C?
The effective resistance between points A and C is 2/3R. Explanation: Effective resistance of ADC is is 2R as they are in series.
What is the difference between effective resistance and equivalent resistance?
Effective resistance is defined as theresistance to an alternating current, expressed as the ratio of the power dissipated to the square of theeffective current. Equivalent resistance is a purely resistive property, which does not change with any other variable.
What are the effective resistances between A and B and D and E respectively?
Now it is series with ED(2Ω). So total =4Ω which in parallel with AD(4Ω). So effective between A and D is 2Ω.
What is the total resistance across A and B in the circuit?
∴ Equivalent resistance between A and B RAB=4∥4=4+44×4=2Ω
What is the equivalent resistance between A and B in the given figure?
Hence, the value of the resistance in the circuit between A and B is 3 ohms.
What is the maximum resistance which can be made?
Hence, the maximum resistance which can be made using five resistors each of 1/5 ohm is 1 ohm.
What is the minimum resistance which can be made?
Hence, the minimum resistance which can be made using five resistors each of 1/5 ohms is 1/25 ohms.
What is the maximum resistance which can be made using 4 resistors?
2 Ohms
How do you find the minimum resistance?
While equivalent resistance increases when resistors are joined in series e.g., Req = R₁ + R₂ + R₃ + …. + Rn. it Means, we can get minimum resistance when all the given resistors will join in parallel. And we can get maximum resistance when all the resistors will join in series .
What is the minimum resistance which can be made using 4 resistors each of 4 ohm?
Answer. Answer: 5 ohm is the minimum resistance we get.
In which combination the value of resistance is maximum and minimum?
The value of resistance is maximum when the resistance are connected in series combination. The value of resistance is minimum when the resistance is connected in parallel connection.
Which combination of current is minimum?
Solution : In parallel combination of cells the voltage across the terminals is same and resistance is minimum. Therefore from V=IR. The current drawn from cell combination will be more.
Why the current is maximum in series and minimum in parallel?
Answer: In series combination of resistance, resistors aid up and opposes the current. In parallel combination, equivalent resistance will be less therefore current drawn will be maximum. For maximum current, resistance should be as small as possible that is achieved by parallel combination.
