When 4 ohm 6 ohm and 8 ohm are connected in circuit find the minimum and the maximum resistance possible?
Minimum resistance is obtained by connecting all three resistances in parallel => 1/R =1/4+1/6+1/8 =>1/R = 6/24+4/24+3/24 => 1/R = 13/24 => R =24/13 ohm . Hope it helps you.
What is the total resistance when two resistors 4 ohm and 6 ohm are connected in parallel?
Hence , Total resistance for series combination is 10
What will be the lowest resistance possible in joining 4 ohm 6 ohm and 12 ohm resistors?
Hence, the lowest resistance is 2 ohms.
What is the current in a wire attached to a 4 ohm resistor with a 12 V battery?
3 Amps
In this circuit, each resistor has a ΔV of 12 Volts. The 12-ohm resistor would have a current of 1 Amp (using Ohm’s law equation) and the 4-ohm resistor would have a current of 3 Amps (using Ohm’s law equation). 6. A 12-V battery , a 12-ohm resistor and a 4-ohm resistor are connected as shown.
What is the total resistance if three resistance of 4 ohm and 6 ohm are connected in parallel?
Answer Expert Verified for getting effective resistance of 4 ohms from 6 ohm resistors, we can put two resistors in series, and their equivalent resistance = 12 ohms. Then connect the third resistance of 6 ohms in parallel. equivalent resistance = 12 * 6 /(12+6) = 4 ohms.
What do you mean by parallel combination of resistors?
Resistors are in parallel when one end of all the resistors are connected by a continuous wire of negligible resistance and the other end of all the resistors are also connected to one another through a continuous wire of negligible resistance. The potential drop across each resistor is the same.
What is the total resistance if two resistance of 4 ohms are connected in parallel?
So, the combined resistance of the system in parallel is 2.67 ohms. Hence, this is the required solution.
What is the total resistance if two resistance?
If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor. That is equal to R/2 and for three equal resistors in parallel, R/3, etc.
What is the lowest resistance that can be obtained by combining 4 coils of resistance 4 ohm 8 ohm 12 ohm 24 ohm?
Electricity. What is (a) the highest, (b) the lowest total resistance that can be secured by combinations of four coils of resistance 4 Ω, 8 Ω, 12 Ω, 24 Ω? R = 4 + 8 + 12 + 24 = 48 Ω.
What is the lowest resistance that can be obtained by combining four coils of resistance 4 Ω 8 Ω 12 Ω and 24 Ω?
2 ohms
There are four coils of resistances 4 Ω, 8 Ω, 12 Ω and 24 Ω, respectively. hence, R=2 ohms is the least value of resistance that we can get from all of the above 4 resistors combinations.
What is the current flowing through 4 ohm resistor?
Hence, the current flowing through 4 Ω resistor is 1 ampere.
How is a 2 ohm resistor connected to a 4 ohm battery?
A 2 ohm resistor and a 4 ohm resistor are connected in parallel to a 6 volt battery. The power dissipated by the 2 ohm resistor is:
How are resistors connected to each other in parallel?
For resistance in the parallel ,voltage across each resistor is same and total current is sum of current through each resistor. Potential difference across each resistance remains same in parallel . Then use Ohm”s law. In your opinion, what would be the average initial startup cost for product development?
