4B.1 Series and Parallel circuits

Question 1

charge within a ciruit cannot

Answer 1

increase for decrease when the circuit is functioning

Question 2

currents in a series circuit

Answer 2

any group of components in a series circuit will have the same current following through the

Question 3

currents in a parrel circuit

Answer 3

when the current faces a junction it will split along different paths, with the path that was less resistant having more current (the branches must add up to the original total current) (I total= I1 +I2 +13)

Question 4

voltages in a series of circuits

Answer 4

the sum of the voltages across the components in a series circuit is equal to the total emf supply (V total = V1 + V2 +V3)

Question 5

voltages in parallel circuits

Answer 5

the voltage of two components across a parallel circuit is identical

Question 6

how can resistance be calculated

Answer 6

using ohms law R= V/I

Question 7

what are the rules for resistors in a series circuit

Answer 7

R Total = R1 + R2 + R3 in a circuit that has no junctions, the total resistance would equal the sum of each individual resistor

Question 8

how do we derive R Total = R1 + R2 + R3

Question 9

how can we calculate the total resistance of resistors in a parallel circuit

Answer 9

1/Rtotal = 1/R1 + 1/R2 + 1/R3

Question 10

how do you derive this formula 1/Rtotal = 1/R1 + 1/R2 + 1/R3
