Instructions

- A 5 ohm resistor and 10 ohm resistor are connected in series. Compared to the potential drop across the 5 ohm resistor, the potential drop across the 10 ohm resistor is
- smaller
- greater
- the same
- greater if St. Mary's wins the States in hockey

- If three resistors of 3 ohms, 6 ohms, and 9 ohms are connected in parallel, the combined resistance will be
- greater than 9 ohms
- between 6 ohms and 9 ohms
- less than 3 ohms
- between 3 ohms and 6 ohms

- A 5 ohm and a 10 ohm resistor are connected in parallel. Compared to the current in the 10 ohm resistor, the current in the 5 ohm resistor will be
- the same
- twice as great
- one-half as great
- one-third as great

- If three resistors, each having a resistance of R ohms, are connected in parallel, their equivalent resistance is
- R/3 ohms
- R ohms
- 2R ohms
- 3/R ohms

- As additional resistors are connected in parallel to a source of constant voltage, the current in the circuit
- decreases
- increases
- remains the same
- increases only after the St. Mary's Hockey team wins the States
