Doubling the resistance in a circuit will increase or decrease amperage?
If voltage remains constant and resistance is increased, the amperage will decrease per Ohm's Law.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance

How is electrical resistance decreased?
Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity. In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.
What are the two ways of decreasing current in a standard test circuit?
Increase the resistance (ohms) Decrease the voltage (Volts)
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
