Answer 8

I= V/R

Question 9

formula for Voltage

Answer 9

V= (I)(R)

Question 10

Question 11

are unrelated to the resistor values in ohms. They serve only to identify one resistor from another.

Answer 11

Series Circuit

Question 12

The basic idea of a “parallel” connection, on the other hand, is that all components are connected across each other’s leads. In a purely parallel circuit, there are never more than two sets of electrically common points, no matter how many components are connected. There are many paths for current flow, but only one voltage across all components.

Answer 12

Parallel Circuit

Question 13

Only has one Electric circuit

Answer 13

Series Circuit

Question 14

Form more than one continuous path rather than one

Answer 14

Parallel circuit
