5. Four wires meet at a junction. It is assumed that two currents, I1 and I4, enter the node. An ammeter records a value of +4A for I1. Currents I2 and I3 are travelling out of the node. I2 has 3A running through it, and I3 has 0.5 A running through it. What is the current in I4?

-0.5 A

0.5 A

-1.5 A

1.5 A

6. True or false: if one obtains a negative current using Kirchoff's current law, it means that the assumed direction of that current was incorrect.

7. True or false: An ammeter is connected in series with the current it is trying to measure?

8. True or false: A voltmeter is connected in series with the voltage it is trying to measure?
