Resistance is the opposition to the flow of the current

Increase Resistance = Current Decreases
Decreases Resistance = Current Increases

Resistance is measured in Ω (pronounce it O-WU-NM-S)]]> 2018-03-06 03:21:11 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/238439594 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/238439601 2018-03-06 03:21:15 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/238439601 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/238439980 2018-03-06 03:23:34 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/238439980 lee519951 https://padlet.com/kim491591/fd5ttq0mouns/wish/238440271 2018-03-06 03:25:18 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/238440271 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239513371 State: It does not obey Ohm's Law (Non-Ohmic)
Describe: Curved gradient
Explain: I is not proportional to V; Therefore resistance is not constant - it changes.]]> 2018-03-08 06:07:02 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239513371 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239513748 State: It does obey Ohm's Law (Ohmic)
Describe: Straight line gradient going through origin
Explain: I is directly proportional to V; Therefore resistance is constant.

This is because there isn't a lot of space for the electrons to move

Thick Wires = Low Resistance
This is because there is more space for the electrons to move]]> 2018-03-08 06:11:47 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239514011 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239514084 When gradient is less steep = Higher resistance

This causes the positive ions to gain more kinetic energy
So they vibrate more
Making it harder for electrons to flow

Hot Wire = High Resistance
Cold Wire = Low Resistance]]> 2018-03-08 06:29:39 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239516587 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239517096 2018-03-08 06:34:13 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239517096 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239517178 2018-03-08 06:34:57 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239517178 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239517331 2018-03-08 06:36:25 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239517331 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239517443 2018-03-08 06:37:35 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239517443 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239518469 We found that a fixed resistor obeyed Ohm's Law whereas a lightbulb did not. This could be seen through the graphs; the graph for the fixed resistor had a straight gradient going through the origin, whereas the graph for the lightbulb had a curved gradient. Since the gradient of the lightbulb graph is curved, it means that current (I) is not proportional to potential difference (V). For the fixed resistor, however, is directly proportional because it has a straight line gradient going through the origin.]]> 2018-03-08 06:45:49 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239518469 lee519951 https://padlet.com/kim491591/fd5ttq0mouns/wish/239519811 2018-03-08 06:55:01 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239519811 kim491591 https://padlet.com/kim491591/fd5ttq0mouns/wish/239520043 2018-03-08 06:56:58 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/239520043 https://padlet.com/kim491591/fd5ttq0mouns/wish/241202755 what can you say for Resistance in both of these? ]]> 2018-03-13 04:37:59 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/241202755 https://padlet.com/kim491591/fd5ttq0mouns/wish/241202775 2018-03-13 04:38:13 UTC https://padlet.com/kim491591/fd5ttq0mouns/wish/241202775
