SCIENCE WITH KYRA-LEE

This week in science, we are learning about Circuits and the different types of circuits: A circuit is a complete loop of electricity flowing around ending &  starting at a power source. There are two main types of circuits; a parallel circuit and a series circuit. 

Example of a parallel circuit and a series circuit involving 2 batteries, 2 bulbs, and a switch:

Parallel circuit-

Series circuit-

                                

What is voltage?

- A volt is the amount of energy in the circuit. The volts can be measured using a voltmeter. In a series, the volts are shared with all the components, but in a parallel circuit, the voltage is the same everywhere.

What is current?

- Energy is measured in amps. A current shows how many amps are flowing in a circuit. We can measure the number of amps in a circuit by using an ammeter. The current in a series is the same everywhere but in a parallel circuit, the current is divided between the components.
