Current Electricity

Question 1

What is a source/battery?

Answer 1

Gives energy to electrons

Question 2

? Prevents disasters:opens the circuit if too much electricity is flowing through

Answer 2

Safety device

Question 3

Transforms electrical energy to other forms of energy

Answer 3

Load

Question 4

Wire is a ?

Answer 4

Pathway for electrons

Question 5

Opens or closes electrons

Answer 5

Switch

Question 6

Open circuits are?

Answer 6

Circuits that have gaps in between the wire

Question 7

Why was a switch designed

Answer 7

To close(no gap;flowing electrons) and to open(gap:no flow) the circuit

Question 8

Are electrons flowing if the circuit is open?

Answer 8

NO

Question 9

If electrons can’t return to source they?

Answer 9

Stay put

Question 10

Open circuits are from
:

Answer 10

Wires that fall off or burnt load(wires inside load falls off)

Question 11

Short circuit electrons move although?

Answer 11

They do not pass through all the loads

Question 12

What if there is still current flowing through when returning to source

Answer 12

Cause a fire or disaster

Question 13

Short circuits are from:

Answer 13

Wires that fall off and reconnect somewhere else

Question 14

An example of safety device

Answer 14

Fuse

Question 15

What is current(I) measured by?

Answer 15

Ampere or amps; A

Question 16

What is current?

Answer 16

Amount of electrons flowing through a circuit

Question 17

Why think of current like water?

Answer 17

Turn tap once = slow, less electrons and turn tap thrice= fast, more electrons

Question 18

Electrons bump into each 9ther and the wall

Answer 18

Resistance
