Question

Which three of these statements about current and voltage in a series circuit are true ?

1. currents are used up in a circuits
2.voltage in a series circuit is divided
between the components
3.if an extra component is added to a series circuit , the current around the circuit decreases
4.the current is the same in all parts of a series circuit
5.if an extra components is added to a series circuit , the voltage across the other components increases
6.the voltage across each component in a series circuit is the same as the supply voltage

Answer 1

1).  No.  In a series circuit, the current leaving the battery is the same as the current arriving back at the battery at the other end of the circuit, and the same as the current at every point around the circuit.

2).  True.
3).  True
4).  True

5).  No.  See #3.

6).  No.  See #2.
