RATE what does it mean?

per unit time

New cards
2

unit for resistance

ohms

New cards
3

POTENTIAL DIFFERENCE what is it?

measure of the electrical work done (J) for every coulomb of charge that flows through a component

New cards
4

what is POTENTIAL DIFFERENCE measured in?

(v) volts

New cards
5

E ?

energy (J)

New cards
6

Q ?

charge (coloumbs)

New cards
7

V ?

(volts)

New cards
8

ohms law ?

current through a resistor is directly proportional to the potential difference across the resistor

New cards
9

formula for PD ?

v = IR

New cards
10

V = IR ?

potential difference = current x resistance

New cards
11

if the charge increases by 2 how much will current increase by ?

2

New cards
12

in a voltmeter how is PD shared ?

it is shared equally

New cards
13

PD in a parallel circuit?

across each branch the pd is the same and is equal to the cell voltage

New cards
14

current in a parallel circuit?

current splits at a junction means that the sum of all the current through each branch equals the total current.

New cards
15

PD in a series circuit?

the potential difference splits between components

New cards
16

current in a series circuit?

the current is the same through each component

New cards
17

what do use to measure current?

ammeter

New cards
18

what do you use to measure potential difference?

voltmeter

New cards
19

what does LDR stand for?

light dependant resistor

New cards
20

rule for light intensity in LDR

as the light intensity increases the resistance of the LDR decreases.

as the light intensity decreaes the resistance of the LDR increases.
