If the two resistors are in series, then the larger one is 2 ohms.
(The smaller one is 1 ohm. Their combined series total is 3 ohms. 9/3 = 3 amps.)
If the two resistors are in parallel, then the larger one is 9 ohms.
(The smaller one is 4.5 ohms. The combined parallel total is 3 ohms. 9/3 = 3 amps.)

What is the combined resistance of a 39k and a 47k resistor connected in series?
86k. Resistance in series is the sum of the individual resistors.
Resistors A and B are connected in parallel If resistor B has twice the resistance of A what is the current taken by resistor B?
half of the current flowing thru resistor 1.... V=IR.
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
Do 5 1 ohm resistors equal 1 5 ohm resistor?
it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
What will happen to the other resistor if the number of resistor decreases?
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
What is the combined resistance of a 39k and a 47k resistor connected in series?
86k. Resistance in series is the sum of the individual resistors.
What is the net resistance of two resistor connected in series?
The net resistance of two resistors connected in series is the sum of the two resistances. RSERIES = Summation1toN RN
Resistors A and B are connected in parallel If resistor B has twice the resistance of A what is the current taken by resistor B?
half of the current flowing thru resistor 1.... V=IR.
Will current flow in a higher resistance or in lower resistance if they are connected in parallel to a voltage source?
Current will always flow in both resistors, but the one with the lower resistance will have more current flow through it. The value of the current in each resistor is calculated by dividing the voltage of the source by the resistance of the individual resistor. As long as the capability of the power source isn't exceeded, the current through each resistor isn't affected by the presence of the other resistor. Said another way, if two resistors are connected in parallel across a source, neither one "cares" that the other resistor is connected across the source. The two resistors work independently.
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the effective resistance of the three resistors?
The effective resistance of those three resistors in parallel is 20 ohms. And it makes no difference what the power source is, or whether they're even connected to a power source at all. As soon as those three resistors are in parallel, their effective resistance is 20 ohms immediately, even if they're still in the drawer.
Do 5 1 ohm resistors equal 1 5 ohm resistor?
it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
