1. 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.

15. The component of a simple electrical circuit
are:
power source, connecting wire, switch and
a load.
• The battery/power source provides energy in the
simple electrical circuit.
• The connecting wires provide the passage of
electricity
• 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.
16. In a closed circuit, there is a continuous
flow of electrons.
In an open circuit, there is an
uninterrupted flow of electrons.
17. Yes, because lighting fixtures and
appliances are compose of the simple
electrical component such as load, switch,
wire and power source.
