What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
When a circuit consists of a capacitor and a resistor in series with a voltage source and the voltage across the resistor becomes zero then the capacitor is?
fully charged.
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
The resistor in an R-L series circuit has a voltage drop of 53V and the inductor has a voltage drop of 28V what is the applied voltage of the circuit?
The applied voltage is 53+28 = 81V.
What does a resistor do in an electric circuit?
Limits current flow and drops voltage.
What work resistor?
when a resistor is connected in a circuit it drop some voltage across it.when a circuit have large input voltage then by using a resistor of suitable value we get the desired voltage.
What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
What is a function of a resistor in a fire alarm circuit?
A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. The resistor has a calibrated and known voltage drop and current while the circuit is "normal". If there is a short-circuit, or an open-circuit, the voltage and current will change and trigger the trouble alarm.
If the resistance in the circuit is increased what will happen to the current and voltage?
* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.

Which resistor of a series circuit receives the larget voltage drop?
The resistor with the most resistance.
When a circuit consists of a capacitor and a resistor in series with a voltage source and the voltage across the resistor becomes zero then the capacitor is?
fully charged.
What is the use of resistor in the circuit?
A resistor develops a voltage differential when current is passed through it. Ohm's law: Voltage is current times resistance.
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
