What has a larger current the parallel circuit with 1 resistor or the parallel circuit with 2 resistors?
By Ohm's law, current is voltage divided by resistance.
In order to determine which circuit draws more current, you need to look at voltage and resistance. Assuming similar voltage, then, less resistance would result in more current.
Now you need to know the values of the resistors in both cases. You did not state those important pieces of information. The net resistance of two resistors, R1 and R2, in parallel is R1 time R2 divided by (R1 plus R2). All you need to do is calculate for the two cases.
If the two resistors were the same, you can generalize the answer by saying that, with contant voltage, two similar resistors in parallel will pull more current than one similar resistor - specifically, two will pull twice the current of one.
What else can I help you with?
What are the relations between individual voltages and the total voltages when resistors are connected in series and in parallel?
-- The current in each individual resistor is (voltage across the whole circuit) divided by (the resistance of the individual resistor). -- The current in any individual resistor is less than the total current in the circuit. -- The total current in the circuit is the sum of the currents through each individual resistor.
What is the current flow in a 12VDC circuit with two 24 ohm resistors in parallel?
In a parallel circuit, the same (supply) voltage will appear across each branch. So, in your example, 12 V will appear across each of the 24-ohm resistors. To find the current through each resistor, then, you simply divide the supply voltage by the value of that resistor. Since the supply current is the sum of the two branch currents, to find the supply current, you simply add together the currents passing through each resistor.
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.
When resistors are connected in series in a circuit. what are the relationships between the voltage drops across the resistor and the currents through the resistors?
When resistors are connected in series in a circuit . the voltage drop across each resistor will be equal to its resistance, as V=IR, V is direct proportional to R. An A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source
What is resistance on something that is shorted?
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors?
False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.
When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
What are some series parallel circuits practice problems that I can solve to improve my understanding of electrical circuits?
Here are some series-parallel circuits practice problems you can solve to improve your understanding of electrical circuits: Calculate the total resistance in a circuit with two resistors in series and one resistor in parallel. Determine the current flowing through each resistor in a circuit with three resistors in parallel. Find the voltage drop across each resistor in a circuit with two resistors in series and one resistor in parallel. Calculate the total power dissipated in a circuit with resistors connected in both series and parallel configurations. Determine the equivalent resistance of a complex circuit with multiple resistors connected in series and parallel. Solving these practice problems will help you develop a better understanding of series-parallel circuits and improve your skills in analyzing and solving electrical circuit problems.

What is true of a series circuit that has two resistors?
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
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
Does a parallel circuit have more than 1 resistor?
Parallel circuits normally have more than one resistor. Basically parallel circuits are circuits where the current has more than path to follow. However, there are parallel circuits where there are two switches rather than two resistors.
How do resistors affect a circuit?
It reduces the current. As the current travels through the resitors it has some current that is left in the resistor. And

What remains constant in series circuit?
A: No matter how many resistor of different value are inserted the current will remain the same for each. The voltage drop will vary with the difference in resistors and i a parallel path is found along the way the current will divide according to the resistors values
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?
