What is the total resistance of a circuit with three 30 ohm resistors in parallel?

So the 3 Resistors each 30 Ohms are connected in parallel. Their Resultant Resistance = 30*30/(30+30 ) =15*30/(15+30)=10 Ohms. Therefore the combined Resistance value is 10 Ohms with an increased power rating.

How will you connect three resistors to get maximum resistance?

To obtain a combined resistance of 9 ohms, three resistors each of resistance 6 ohm should be connected in a parallel circuit and one in series. In a parallel circuit, the equivalent resistance of all the resistors connected is equal to the reciprocal value of the sum of the individual resistances.

How do you calculate total resistance?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

How can three resistors of resistance 2 ohm 3 ohm and 6 ohm connected to give a total of 4 ohm?

There are three resistors of resistances 2 Ω, 3 Ω, and 6 Ω respectively. This equivalent resistor of resistance 2 Ω is connected to a 2 Ω resistor in series. Therefore, the equivalent resistance of the circuit = 2 Ω + 2 Ω = 4 Ω Hence the total resistance of the circuit is 4 Ω.

How would you join the three resistors of 9 Ohm each so that net resistance of combination becomes 6 ohm?

The first two resistors would be connected in parallel and third one is connected in series with the first two parallel resistors. (b) Image 2: For equivalent resistance to be 6 ohm, the following arrangement of combination of 9 ohm each resistance has to be joined in circuit of three resistance.

How can three resistors of resistance?

To obtain a total resistance of 4 Ω from three resistors of given resistances, Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance. Hence, the total resistance of the circuit is 4 Ω. ⇒ 1/R = 1 Ω.

What is the equivalent resistance of a 3000 ohm resistor in series?

The 3000 ohm resistor in series is additive. So the aggregate resistance is 4500 ohms. A 2 ohm and 3 ohm resistor are connected in series, and are both connected in parallel with a 5 ohm resistor. What is the equivalent resistance of this setup in ohms?

How do I convert 30 ohm resistor to 15 ohm?

Put 2 resistors in parallel. The resultant is 15. Put third resistor in series to get 15+30=45. Put 2 resistors in series, get resultant as 60. connect two 30 ohms resistors in parallel first. Then you will get 15 ohms. Now connect remaining 30 ohm resistor in series.

How do you calculate effective resistance of a parallel circuit?

The calculation for resistors in parallel is the reciprocal of the sum of the reciprocals of each resistance. for getting 45 ohms connect two resistance in parallel so combination of two resistance give effective resistance = (30*30)/ (30+30)=15 ohms and this resistance connect in series with 30 ohms so final effective resistance is =30+15=45

What is the total resistance when R1 is in series?

If a series–parallel circuit has all 30-ohm resistors, what is the total resistance when r1 is in series with a parallel circuit consisting of r2 and r3? If a series–parallel circuit has all 30-ohm resistors, the total resistance when r1 is in series with a parallel circuit consisting of r2 and r3 is color (red) (45ohms).
