A student tests a piece of resistance wire. A battery, a fixed resistor, an ammeter and the resistance wire are connected in a single closed loop. The ammeter is connected between the battery and the fixed resistor. In 24 s, 3.6 C of charge passes through the ammeter.
Calculate the reading on the ammeter.
The ammeter is moved to the other side of the resistance wire. Give the new reading on the ammeter. Explain your answer in terms of charge.
