Elcectrical Circuits

What is an electrical circuit?

Is a closed path along which electrons can flow.

What is an open circuit?

Contains a gal or break that stops the continuous flow of electrons

What is a Closed circuit?

No breaks of gaps, allowing electrons to flow continuously through a circuit

What is an electric current?

This refers to the rate of movement pf electric charge. This is represented using a unit called a Column (C)

How do you measure a current?

Using an Ampere or amp (A)

Wha is the current of a circuit?

1A (which mean that 1C of charge passes a given point in the circuit ever second)

True of False: the amount of current is the same at every point in the current

True, the current does not change

What is electrical resistance?

Electrical resistance is the “slowing down” of the current through a circuit.

Which is then converted into other forms of energy: light, sound or heat.

How is electrical resistance measured?

Electrical resistance (R) is measured using the ohm symbol.

What is the name of the device used to decrease the current.

A resistor

True or False: an electrical load is not a resistor.

False, an electrical load IS a resistor

What is a load?

Is a resistor of any other devise that converts electrical energy into other forms of energy such as: light, heat or motion and sound. Any item within a circuit that uses the electrical energy is a load.

What are some example of a load?

A light bulb, a TV or a Printer

What is Voltage? (Or potential difference)

Is the difference between the electrical potential energy at two points in a circuit.

How is Voltage measured?

Voyage (V) of s measured in Volts (V)

What is the voltage of the average battery?

1.5 volts

What is a Volt?

A volt can be described as a “push”

What do batteries use to separate charges?

Batteries use potential energy

What are the four parts of an electric circuit?

1: source-something that produces electrical energy

2: electrical load-something that converts electrical energy into a usable form

3: control devices-a simple switch that controls the circuit

4: connectors-something that provides a controlled path for electric current to flow to each part of the circuit

What is an example of an electrical circuit?

Open switch - Closed switch

How is current measured?

Electric current is measured using an Ammeter. Which are connected in series in a circuit.

how is voltage measured?

Voltage (or potential difference) is measured using a voltmeter.

How to connect a voltmeter?

Voltmeter In Parallel (VIP)
