Which of the following are characteristics of series circuits? Select all that apply. The voltage is divided among all devices in the circuit.The same amount of current flows through all devices in the circuit.If one device in the circuit stops allowing current to flow, all other devices in the circuit will also stop functioning.The voltage across each device must be the same.There are multiple paths for current to follow through the circuit.There is only one path for current to follow through the circuit.

An old hair dryer has two switches. If the first switch is turned on then the hair dryer blows cold air.When the second switch is also turned on, then hot air is blown. When only the second switch is on, then neither the fan, nor the heating element are working. Draw a circuit diagram of the hair dryer.

When unequal resistors are connected in series across an ideal battery, the same power is dissipated in each one. the equivalent resistance of the circuit is less than that of the smallest resistor. the potential difference across each is the same. the equivalent resistance of the circuit is equal to the average of all the resistances. the current flowing in each is the same.

Voltmeters can be used to determine the voltage difference between two points on a circuit. An ammeter can be used to determine the current at any given location on a circuit. The circuit at the right is powered by a 12.0-volt battery and utilizes two voltmeters and two ammeters to measure voltage drops and currents. The resistor values are 1.28 Ω (R1) and 3.85 Ω (R2). Determine the ammeter readings and voltmeter readings.
