Quick Answer: What Is The Minimum Number Of 2 Ohm Resistance Can Be Connected?

What is maximum effective resistance?

Maximum effective resistance will be when all the resistors are in series combination.

So, Reffmax=n R.

Minimum effective resistance will be when all the resistors are in parallel combination..

How do you find the minimum resistance?

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 . ∴ for finding minimum resistance , we have to join all resistors in parallel.

How do you know if a series resistor is parallel?

The trick is to look at the nodes in the circuit. A node is a junction in the circuit. Two resistor are in parallel if the nodes at both ends of the resistors are the same. If only one node is the same, they are in series.

What is the effective resistance between A and B?

therefore the effective resistance between A and B is 10Ω

When an unknown resistance and a resistance of 4 ohm are connected?

When an unknown resistance and a resistance of 4Ω are connected in the left and right gaps of a meterbridge, the balance point is obtained at 50 cm. the shift in the balance point if a 4Ω resistance is now connected in parallel to the resistance in the right gap is.

What is the minimum number of 2 ohm resistance?

Hence, 6 resistance of 2Ω are required.

Can I put 2 resistors in series?

You can place more than two resistors in series if you want. You just keep adding up all the resistances to get the total resistance value. For example, if you need 1,800 Ω of resistance, you could use a 1 kΩ resistor and eight 100 Ω resistors in series. Here, the two circuits have identical resistances.

Is current the same in series?

The same current flows through each part of a series circuit. … Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.

What is the value of 2 ohm resistance Current?

2.1 A.Answer. Answer: The current through 2 ohm resistor is 2.1 A. Hence, the current through 2 ohm resistor is 2.1 A.

Is more power dissipated in series or parallel?

The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source.

What is the highest value of resistance?

Resistors. A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’.

What is nominal resistance?

Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value the resistor was designed to have. The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be. … The fifth band tells you the tolerance.

What is the minimum number of 2 ohm resistance can be connected to an effective resistance of 1.5 ohm?

4 resistorsHence, if we use 4 resistors of 2 ohm each, then the equivalent is equal to 1.5 ohms.

What is the effective resistance?

the resistance to an alternating current, expressed as the ratio of the power dissipated to the square of the effective current.
