Heavenly Father,

we praise and glorify Your name.

We are humbly asking for Your guidance throughout this day.

May we have the wisdom to understand the lesson we will have today.

Let Your light shine to those who are in the midst of darkness and those who

are in lack of hope.

May they be enlighten by Your grace and lead them back to You.

We are thankful today that we are alive and well.

That we are given another chance to partake with the fullness of life.

Most especially have the opportunity to do good and be of service to mankind.

AMEN.

A simple circuit is anyarrangement of materials thatpermits electron to flow through it.

+-

The component of a simple electrical circuitare:

power source, connecting wire, switch anda load.

• The battery/power source provides energy in thesimple electrical circuit.

• The connecting wires provide the passage ofelectricity

• The switch serves to open or close the circuit.• The load/bulb works when all of the component

are present and when the circuit is closed.

In a closed circuit, there is a continuousflow of electrons.

In an open circuit, there is anuninterrupted flow of electrons.

Yes, because lighting fixtures andappliances are compose of the simpleelectrical component such as load, switch,wire and power source.
