Electricity

Question 1

What is electricity

Answer 1

Movement of electrons

Question 2

What is static electricity

Answer 2

Stationary charge

Question 3

What is dynamic electricity

Answer 3

Charges moving due to electric field, creates current

Question 4

What is a conductor

Answer 4

Electricity flows through, usually metal

Question 5

What is a insulator

Answer 5

Blocks electricity, e.g. rubber, glass, wood

Question 6

What is a semi conductor

Answer 6

Electricity normally cannot flow through but with enough energy it can

Question 7

What is a super conductor

Answer 7

Electricity flows through with zero resistance, very low temps required

Question 8

What is charge

Answer 8

Number of electrons

Symbol - q

Question 9

What are the units for charge

Answer 9

Coulomb (C)

Question 10

What is current

Answer 10

The rate of flow

Symbol - I

Question 11

What are the units for current

Answer 11

Amperes (A)

Question 12

What is the formula for current

Answer 12

I = q/t
1A = 1C/sec

Question 13

What is voltage (potential difference)

Answer 13

Energy put into and used in a circuit

Symbol - V

Question 14

What are the units for voltage

Answer 14

Volts (V)

Question 15

What is the formula for voltage

Answer 15

V = E/q

Question 16

What is resistence

Answer 16

How much a component resists electrons

Symbol - R

Question 17

What are the units for resistence

Answer 17

Ohms (omega)

Question 18

What does “in series” mean

Answer 18

Components are connected one after the other

Same current though all the components

Question 19

What does “in parallel” mean

Answer 19

Components split the circuit into multiple paths

Current is force to split up to pass through components
