It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load.
To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow.
To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
What else can I help you with?
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
An electric dc circuit is attached to a 12 volt battery and has a 3ohm resistor in it What is the current flowing through the circuit?
The current depends on the total effecvtive resistance of everything connectedacross the battery.If the resistor is the only component there, then the current is E/R = 12/3 = 4 amperes.
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
What does a series circuit not have?

When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
Resistor and capacitor built circuit for alarm switch?
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
What size resistor do you need to drop 18 volts dc to 16 volts dc?
To drop 18 volts DC to 16 volts DC, you need a resistor that can handle the current flowing through the circuit. The voltage drop required is 2 volts (18V - 16V). To calculate the resistor value, use Ohm's Law (V = I × R); rearranging gives R = V/I. The specific resistor value depends on the current (I) in the circuit. For example, if the current is 1 amp, you would need a 2-ohm resistor (2V/1A = 2Ω).
What ll be effect if resistor in snubbing circuit is opened?
The resistor in the snubbing circuit is there to minimize the reverse EMF spike that occurs when a DC inductive load, such as a relay coil or other electromagnet is released. Opening the snubbing circuit will expose the driving circuit to high voltage transients that can damage it.

How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
What to expect if a resistor is placed in a dc circuit with a capacitor?
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Does tube light work with ac or dc?
Fluorescent lights work just fine on DC voltage, BUT one needs a current limited power source to stabilize the circuit against the negative resistance of the gas discharge. This can be done with either a resistor or an electronic circuit. The resistor solution is too lossy because excess voltage from the dc csupply has to be converted to heat across the resistor. Electronic switching supplies could supply a fluorescent light with a dc voltage and current without the losses. But that's technological overkill and most circuits still supply AC.
What is the time constant of a 0.001 microfarad capacitor and a 15000 ohm resistor connected in series in a dc circuit?
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
How does clamper work?
A clamper circuit is an electrical circuit that shifts the DC level of a signal. It consists of a diode, capacitor, and resistor. When a positive or negative peak in the input signal is detected, the capacitor charges or discharges to shift the DC level. This allows the output signal to oscillate around the desired DC level.
