Question 12

If ammeter 1 (A1) and Ammeter 3 (A3) have a current of 4.2 A what is the current through Ammeter (A2)?

Explain yout answer

Answer 12

4.2

The current is the same everywhere in a series circuit: The electric charges are moving at the same speed in all parts of the circuit.

Question 13

Are the lamps in series or in parallel?

In series

Question 14

Are the lamps in series or in parallel?

Answer 14

In parallel

Question 15

Which lamp is in parallel with lamp Q

Answer 15

Lamp P

Question 16

If the current through lamp Q and P was 0.2 A, what would be the current through lamp R?

Explain your answer?

Answer 16

0.4 A

The charges would split when they were moving through lmaps Q and P because they are on different branches but come back together through lamp R.
