Series and Parallel

Question 1

Current in a series circuit

Answer 1

Same everywhere

Question 2

Current in a parallel circuit

Answer 2

Current at each branch added together equals current from supply

Question 3

Pd in a parallel circuit

Answer 3

All the same

Question 4

Pd in a series circuit

Answer 4

Every pd added together equals pd from supply

Question 5

Where should voltmeters go

Answer 5

Over what is wanted to measure

Question 6

What does a diode do

Answer 6

Allows current to flow in ONE direction

Question 7

Difference between LED diode and regular diode

Answer 7

They do the same things but LED gives out light

Question 8

Kirchhoffs 1st law

Answer 8

Total current flowing into a point = current flowing out of that point

Question 9

Kirchhoffs 2nd law

Answer 9

Around any closed loop in a circuit the sum of pds across all components = 0

Question 10

Resistance in a series circuit

Answer 10

Total resistance is all the resistance added up

Question 11

Resistance in a parallel circuit

Answer 11

1/R(total) = 1/R(1) + 1/R(2) + 1/R(3)

Question 12

How is V(total) = V(1) + V(2) + V(3)

Answer 12

Because all energy is conserved
