1
New cards

flow of electrons from the negative to the positive terminal of a battery .

direct current

2
New cards

current reverses its ' direction periodically .

alternating current

3
New cards

Conductors Insulators

2 types of resistors

4
New cards

these are materials that have a very low resistance to current flow . they heat up quickly and cool off quickly ex metals

Conductors

5
New cards

these are materials that have a high resistance to current flow . They heat up slowly and cool off slowly ex ) non metals , glass , rubber , water etc

Insulators

6
New cards

resistors are linked one after the other making only 1 path for the current travel from the - to the + terminal of the battery .

series circuits

7
New cards

resistors are connected in a ladder more than one path for current to travel

Parallel circuits

8
New cards

Rt = R1 + R2 + ......

Series circuit formula for total resistance

9
New cards

1 / Rt = 1 / R1 + 1 / R2 + ....

PARALLEL CIRCUITS : the total resistance formula
