Electric Circuits and Electrical Safety

Question 1

Series Circuit Formulas

Answer 1

I 1 = I 2 (Current is the same at any point)

V = V 1 + V 2 (Voltage is split)

Resistance is added per resistor

Question 2

Parallel Circuit Formulas

Answer 2

1. I = I 1 + I 2 (Current is summed up)
2. V = V 1 = V 2 (Voltage is the same throughout)
3. 1/R = 1/R1 +1/R2

Question 3

What are the advantages and disadvantages of series circuits?

Answer 3

ADV:

1. Less Wires
2. SImple

DISADV:

1. Circuit breaks when one component breaks
2. cannot be controlled individually
3. adding components affect overall performance
