CORRECT ANSWER : b. Current flow is increased from
this area
Question 2: On an impressed current cathodic protection
system, the negative wire of the rectifier is connected to the:
- Anode
- Cathode

- Automatic tank gauging
- Statistical inventory reconciliation
- Soil-vapor monitoring
- Impressed current cathodic protection
CORRECT ANSWER : a. Impressed current cathodic
protection
Question 4: When a tank is temporarily closed, the cathodic
protection system:
