What happens when a resistor is removed from a parallel circuit?

By removing parallel resistance, the total resistance will increase. Therefore, the current will decrease based on ohm’s law V=IR.

What happens when a resistor is removed from a series circuit?

Since the equivalent resistance is the sum of the resistance of the individual resistors, any decrease of resistance or removal of a resistor will lead to a decrease in the equivalent resistance.

When one resistor is removed in a parallel circuit What is the total resistance?

IncreasesWhen the resisters are connected in series resistance of the circuit will be more than the resisters are connected in parallel. Parallel resistor is removed from the circuit the resistance will increase.

When a resistor is connected in parallel to another in a circuit the current flowing through the main circuit?

In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.

What happens if a resistor opens?

Any interruption in the circuit, such as an open switch, a break in the wiring, or a component such as a resistor that has changed its resistance to an extremely high value will cause current to cease. The EMF will still be present, but voltages and currents around the circuit will have changed or ceased altogether.

What happens if resistors connected in series?

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. The total resistance of a number of resistors in series is equal to the sum of all the individual resistances. In this circuit the following applies.

Why does resistance increase when resistor is removed?

This is independent of numbers of resistors and their values. When a resistance is removed in a parallel connection the circuit draws less current ie. because of removing parallel resistance the effective resistance will increase. Supply is given from the electric supply corporation.

What is the effect of using more than one resistor connected in parallel in an electrical circuit?

When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower.
