parrallel

Question 1

what are always connected in a series?

Answer 1

ammeters

Question 2

how do you work out the voltage out?

Answer 2

voltage out = voltage in x resistance _ total resistance

Question 3

what is current?

Answer 3

current is the rate of flow of charge

Question 4

how do you work out the voltage?

Answer 4

voltage = current x resistance

Question 5

how do you work out the resistance?

Answer 5

resistance = voltage _ current

Question 6

how do you work out the current?

Answer 6

current = voltage _ resistance

Question 7

what does LDR mean?

Answer 7

light dependant resistor

Question 8

what happens as the light gets brighter on a LDR?

Answer 8

the resistance decreases and the current increases

Question 9

how do you work out the resistors in series?

Answer 9

Rt = R1 + R2 + R3

Question 10

how do you work out the resistors in a parrallel?

Answer 10

1/Rt = 1/R1 + 1/R2 + 1/R3
