Question

If each resistor in the circuit drawn inside is 5.0 ohms and the battery is 12.0 V, what does the second ammeter (A_2) read?

A. 0.48 A
B. 0.24 A
C. 0.96 A
D. 0.12 A

Answer 1

your circuit is equivalent to this one:

the voltage drop across A and B is
\[{V_{AB}} = \frac{{12}}{{5 + 2.5 + 5}} \times 2.5 = ...volts\]
