"Different Circuit Connections" Electrical PPT

Description

"Different Circuit Connections" Electrical PPT

Part 1: How to connect inside

This is a junction box with 4 binding posts. Inside the box, use wires to connect terminals No. 1 and No. 3 together.

Think about it, how do you know the connections in a junction box without opening the cover?

Use a circuit detector to check which terminals are open and which are open.

Different circuit connections PPT, part 2: Comparing two different circuit connections

Different connection methods of two batteries

Two batteries connected in series Two batteries connected in parallel

What are the characteristics of connecting batteries in series and parallel?

The voltage of a battery is 1.5V.

The voltage of two batteries connected in series is 3V, so the small light bulb will be particularly bright.

When two batteries are connected in parallel, the voltage is still 1.5V, so the small light bulb is not very bright.

What are the characteristics of connecting small light bulbs in series and parallel?

The voltage of a battery is 1.5V.

The voltage of the battery in a two-bulb series circuit is divided between the two lamps, so the smaller bulb is dimmer.

In a parallel circuit of two light bulbs, the voltage across the bulbs is the same as the battery, so the small bulb is brighter.
