Question 1-12 & the different between a parallel and series circuit

1.Can you make the energy ball work? What do you think makes the ball flash and hum?
Yes, I can make the energy ball work, because we complete the circuit, and we are the conductor

2.Why do you have to touch both metal contacts to make the ball work?
We have to touch both metal contacts to make the ball work because we complete the circuit

3.Will the ball light up if you connect the contacts with any material?
The ball only light up with metals, conductors and water

4.Which materials will make the energy ball work?
Metals and water can make the energy ball work

5.This ball does not work on certain individual, what could cause this to happen?
This ball does not work on certain individual skin; where the skin is dry and don’t have any moisture, the ball will only work on the moisture skin.

6.Can you make the energy ball work with 5-6 individuals in your group? Will it work with the entire class?
Yes, it is a complete circuit

7.What kind of a circuit can you form with one energy ball?
Simple circuit

8.Given two balls, can you create a circuit where both balls light up?
Yes, simple circuit

9.What do you think will happen is one person lets go of the other person's hand and why?
The ball will not be light up, because there is no complete circuit.

10.Does it matter who let's go?
No, it does not matter

11.Can you create a circuit where only one ball lights (both balls must be included in the circuit)？
Series and Parallel circuit

12.What is the minimum number of people required to complete this?

5 people is the minimum number of the people required to complete this

What is the different between a parallel and series circuit?
In a series circuit the loads are connected one after another in a single path

In a parallel circuit loads are connected  are side by side
