Study the following statements about several general types of circuits.
Put True or False against each of them. Correct the false ones
1.
In a series circuit the current flows to the negative terminal of the
source.
2. The current does not change in a series circuit.
3. The resistances of each object in a series circuit form the total
resistance.
4. The more objects are in a series circuit, the less voltage there is in the
circuit.
5.
In a parallel circuit the current in each branch and in the source is the
same.
6. The total resistance of parallel objects is the sum of individual
resistances.
7. A parallel circuit has only one path for the electric current.
8. The amount of current in a branch depends on the amount of its
resistance.
