Resistors placed in series create a total resistance that is found by simply adding the values of the resistors. (Knowing the applied voltage isn't necessary to solve this problem.) Rt = R1 + R2 + R3 = 2 ohms + 4 ohms + 6 ohms = 12 ohms

If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
What happens to resistance when resistors are wired in parallel delta circuit?
What do you mean by a 'parallel delta' circuit -is there such a connection.
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
How do you find the resistance of a parallel circuit with n identical resistors?
We have n identical resistors, call them R1, R2 etc up to Rn. All have resistance R. Resistance of the whole circuit = 1/(1/R1 + 1/R2 + ... + 1/Rn) = 1/(n*(1/R)) = 1/(n/R) = R/n So it's the resistance of one resistor, divided by the number of resistors.
What are everyday uses of series circuits?
Your battery-powered flashlight is a good example of a DC series circuit. Battery power is DC. The battery is connected to a wire or piece of metal that's connected to a switch that is connected to an incandescent light bulb (resistor/thermistor) which is then connected to another piece of metal or wire which is connected to usually a spring in the end of the flashlight which creates a ground to the negative terminal of the battery.
What is the equivalent resistance of a circuit that contains two 50.0 resistors connected in series to a 12.0 v battery?
100.0 (apex)
A 24 volt battery supplies three devices wired in parallel that each have a resistance of 9 ohms. What is the voltage drop across each device?
A simple circuit has three resistors connected in series. The resistors are 14 ohms 12 ohms and 9 ohms. What is the total resistance of the circuit?
What is the total resistance of a circuit that contains two 100 resistors connected in paralle?
50 ohms
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
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 total resistance in a circuit that contains three 60 resistors connected in series?
The total effective resistance of resistors in series is the sum of the individual resistances.Three 60-ohm resistors in series have a total effective resistance of (60 + 60 + 60) = 180 ohms.
What is the resistance in a circuit if two 60ohm's resistors are connected in series?
The equivalent resistance of multiple resistors connected in series is the sum of theindividual resistances.(10 + 60 + 50) = 120 ohms for this particular trio of resistors in series.It makes no difference what battery they may be connected to, or if they're connected toany power supply at all.
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.
What is a resistance network?
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
Two resistors are connected in series to a 9 volt battery. The larger resistor provides twice as many ohms resistance as the smaller one. The current through the circuit is 3 amps. What is the resista?
2
What is the equivalent resistance through the entire circuit?
To find the equivalent resistance in a circuit, you need to analyze the circuit configuration. The equivalent resistance for resistors in series is the sum of all individual resistances. For resistors in parallel, the reciprocal of the equivalent resistance is the sum of the reciprocals of the individual resistances. Once you determine how the resistors are connected, apply the appropriate formula to find the equivalent resistance.
