What happens to the current in a circuit if the resistance is increased?

current is the movement of charg carriers (normaly electrons) through a conductive material. the easyest way to think about it is that voltage is like a force pushing on the electrons, and resistance will push back against this. Current is then the result of these two factors. This is where we get the equation voltage=current*resistance. In answer to your question, increasing the circuit resistance will decrease the current in the circuit, as long as the supply voltage stays the same.

∙ 15y agoIf you increase the voltage V, also the current I must go up. R = V / I. The ratio of the resistance stays constant. Scroll down to related links and look at "Ohm's Law".

Ohm's Law: current equals voltage divided by resistance.

Why does less current run through a circuit when there are more loads?
This happens only in pure series circuits, due to increased resistance.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
What happens when a bypass capacitor is shorted?
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
When the resistance in a circuit is increased what happens to the current?
The flow of electrons meets an increased impedance to it's flow.
What happens to the current in a circuit when the resistance is increased?
The flow of electrons meets an increased impedance to it's flow.
What happens to the current in a circuit if the resistance in increased.?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to a circuit if the resistances is increased?
The voltage drop across each resistance will go up, and the current through the circuit will go down.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
What happens when one bulb is added to a series circuit?
The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.
Why does less current run through a circuit when there are more loads?
This happens only in pure series circuits, due to increased resistance.
What happens when the length of the wire in the series circuit is increased?
The current at every point in the series circuit becomes slightly less, because the increased length of wire adds slightly more resistance to the loop.
What happens to the voltage if the current increases?
Yes, if the resistance remains constant. Power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance. In essence, the power increases as the square of the voltage.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
