A 10-ohm resistor is connected in series with another resistor of unknown value. Of the resistances below, which is a possible equivalent resistance of the pair?

12 ohms

A pair of 12-ohm resistors connected in parallel are connected in series with a 6-ohm resistor. The equivalent resistance of this arrangement is

12 ohms.

A 12-ohm resistor is connected in parallel with a 6-ohm resistor. The equivalent resistance of this pair is

4 ohms.

In a series circuit, if the current in one lamp is 5 amperes, the current in the battery is

5 A.

A 10-ohm resistor is connected in parallel with another resistor of unknown value. Of the resistances below, which is a possible equivalent resistance of the pair?

6 ohms

A pair of 12-ohm resistors are connected in parallel. The equivalent resistance of this pair is

6 ohms.

As more lamps are connected to a series circuit, the overall current in the power source

decreases.

When connecting a safety fuse in a circuit, connect it

in series with the power line.

Consider a compound circuit consisting of a pair of 10-ohm resistors in parallel, which are in series with three 10-ohm resistors in series. The equivalent resistance of the circuit is

more than 30 ohms.

The flow of charge in an electric circuit is

much like the flow of water in a system of pipes.

The amount of current in the filament of a light bulb is

the same as the current in the connecting wires.
