# How are two electrical devices connected in a circuit?

## How are two electrical devices connected in a circuit?

When there are two or more electrical devices present in a circuit with an energy source, there are a couple of basic means by which to connect them. They can be connected in series or connected in parallel.

## How are two resistors connected in a circuit?

The two resistors R1and R2 in Figure 7.3.1 are connected in series to a voltage source∆V. By current conservation, the same current Iis flowing through each resistor. Figure 7.3.1(a) Resistors in series.

How can parallel circuits be explored in the same way?

Using the same collection of wires, D-cells and bulbs, parallel circuits can be explored in the same manner. The effect of the number of resistors upon the overall current and the overall resistance can be investigated. The diagrams below depict the usual means of constructing the circuit with parallel connections of light bulbs.

### How does the type of connection affect the resistance of a circuit?

The means by which the resistors are connected will have a major effect upon the overall resistance of the circuit, the total current in the circuit, and the current in each resistor. In Lesson 4, we will explore the effect of the type of connection upon the overall current and resistance of the circuit.

### What are the two types of electrical connections?

Two Types of Connections. Series Circuits. Parallel Circuits. Combination Circuits. When there are two or more electrical devices present in a circuit with an energy source, there are a couple of basic means by which to connect them. They can be connected in series or connected in parallel.

What kind of wiring is used for multiple outlets?

This wiring allows for source voltage at each outlet independent of the others in the circuit. Here 3-wire cable is run from a double-pole circuit breaker providing an independent 120 volts to two sets of multiple outlets. The neutral wire from the circuit is shared by both sets.

## Which is more common parallel circuit or Series circuit?

What Is a Parallel Circuit? Much more common than series circuits are those wired in parallel—including most household branch circuits powering light fixtures, outlets, and appliances. A parallel circuit is also a closed circuit where the current divides into two or more paths before coming back together to complete the full circuit.
