## When unequal resistors are connected in a parallel circuit?

In parallel connection, all the elements are connected between same two points hence the voltage drop across any number of resistors or other elements connected in parallel is same. Hence C is correct.

## When unequal resistors are connected in series across an ideal battery?

When unequal resistors are connected in series across an ideal battery,the same power is dissipated in each one. the potential difference across each is the same. the current flowing in each is the same. the equivalent resistance of the circuit is less than that of the smallest resistor.

## What can be said about a circuit that contains two unequal resistances in parallel?

Two resistors of unequal resistance are in a parallel circuit. The current through each resistor is the same. An ideal voltmeter would have infinite resistance.

## What happens if resistors are connected in parallel?

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. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst them.

## How do you calculate resistors in parallel?

4. “You can find TOTAL RESISTANCE in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 + ” Before we get into the calculations, remember what we said at the start of this section: “The total resistance of a parallel circuit is NOT equal to the sum of the resistors (like in a series circuit).

## When resistors are connected in parallel which of the following would be the same for each resistor?

4 replies. “In parallel, the potential difference is the same across each resistor. Without knowing individual resistances, nothing can be determined about current or power.”

## Which of the following is true about the total resistance of several resistors connected in parallel?

One important point to remember about resistors in parallel, is that the total circuit resistance ( R_{T} ) of any two resistors connected together in parallel will always be LESS than the value of the smallest resistor in that combination.

## How do you find equivalent resistance?

Solution The equivalent resistance is the algebraic sum of the resistances (Equation 10.3. The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.

## What is the net resistance of the circuit connected to the battery?

The net resistance of the circuit connected to the battery is 1.625R.

## Why battery is used in the circuit?

The key functions of a battery and bulb in a circuit are explained. A battery is a source of energy which provides a push – a voltage – of energy to get the current flowing in a circuit. When the energy in the battery is used up there is no current and the bulb does not light up.

## When the resistances are connected between the same two points they are said to be connected in parallel?

When two or more resistances are connected across two points so that each of them provides a separate path for current, they are said to be connected in parallel. Here the reciprocal of their combined resistance is equal to the sum of the reciprocals of the individual resistances.

## What is voltage drop in a circuit?

Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated.

## How do you know if a series connection is parallel?

REVIEW: In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

## What happens when you remove a resistor from a parallel circuit?

Originally Answered: If a resistor in a parallel circuit is removed, the current through others increases. Suppose we have three resistors connected in parallel and a voltage source connected across them. The current flowing through each resistor is and total current flowing through source is.

## What happens when you put resistors in series?

When resistors are connected in series, the total voltage (or potential difference) across all the resistors is equal to the sum of the voltages across each resistor. In other words, the voltages around the circuit add up to the voltage of the supply.
