Current Electricity

Question 0

what is current electricity

Answer 0

moving electricity (flow of electrons)

Question 1

electricity is highly controlled by paths called

Answer 1

circuits

Question 2

source of electrical energy

Answer 2

• pushes electrons through circuit
• includes generators, solar panels, cells/batteries
• work by separating charge

Question 3

load

Answer 3

• converts electrical energy into the energy we want

- any appliance or electrical device is a type of load

Question 4

Control device

Answer 4

• turns circuit on or off

- circuit will work without a switch

Question 5

connections

Answer 5

wires that connect all the components together

Question 6

types of circuits

Answer 6

• parallel
• series
• complex

Question 7

series circuit

Answer 7

one path for electricity flow

Question 8

parallel circuit

Answer 8

multiple paths for electricity flow

Question 9

complex circuit

Answer 9

combination of series and parallel

Question 10

current

Answer 10

• movement of charges
• measured in AMPS
• the more charges moving past a certain point per second, the higher the current

Question 11

types of currents

Answer 11

• alternating current switches directions a few times per second
• direct current travel in one direction only

Question 12

voltage

Answer 12

• also called potential difference
• measure how much charge separation there is
• the more separation the more potential to do work
• measured in volts

Question 13

resistance

Answer 13

• electrons slow down when they travel through a wire
• the slow down is called resistance
• measured in OHMS
• determined by thickness (less resistance) and length (more resistance)

Question 14

power

Answer 14

• measure how much electrical energy is concerted to useful energy overtime
• measured in watts
• the more electrical energy converted to useful stuff, the more efficient the machine
• in any energy conversion some energy will be lost as heat
