Question
Base your ans wer to the question on the information
and diagram below.
A 20.-ohm resistor and a 30.-ohm resistor are connected
in parallel to a 12-volt battery as shown. An ammeter is
connected as shown.
12 V
20.
30. 2
Figure 1
5. [Refer to figure 1]
What is the current reading of the ammeter?
1. 1.0 A
3. 0.40 A
2. 0.60 A
4. 0.20 A
6. A physics student is given three 12-ohm resistors with
instructions to create a circuit that would have the lowest
possible res istance. The correct circuit would be
1. a series circuit with a total resis tance of 36 ohms
2. a series circuit with a total resis tance of 4 ohms
3. a parallel circuit with a total resistance of 36 ohms
4. a parallel circuit with a total resistance of 4 ohms
