This circuit diagram represents a(n):

69% Answer Correctly

	series circuit
	open circuit
	series-parallel circuit
	parallel circuit

Solution

A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.

This circuit component symbol represents a(n):

70% Answer Correctly

	fuse
	capacitor
	diode
	resistor

Solution

Fuses are thin wires that melt when the current in a circuit exceeds a preset amount. They help prevent short circuits from damaging circuit components when an unusually large current is applied to the circuit, either through component failure or spikes in applied voltage.

3 A circuit with a 120-volt power supply is protected by a 5-amp circuit breaker. What is the largest number of watts loads on this circuit can safely use?

84% Answer Correctly

	598 W
	660 W
	602 W
	600 W

Solution

Wattage is current multiplied by voltage: W = IV. So, the maximum amount of power a 120-volt circuit with a 5A circuit breaker would allow is 120V x 5A = 600 W.

In a series circuit, which of the following is the same across all branches of the circuit?

61% Answer Correctly

	current
	resistance
	conductance
	voltage

Solution

Which of the following is a characteristic of batteries connected in series?

62% Answer Correctly

	total voltage equals the sum of the individual battery voltages
	total voltage equals the average of the individual battery voltages
	the positive terminal of one battery is connected to the positive terminal of the next
	two connections are made between each adjacent battery

Solution

You can multiply the voltage or the current supplied by individual batteries by connecting them together either in series or in parallel. The characteristics of batteries connected in series are that total voltage equals the sum of the individual battery voltages, total current equals the average of the individual battery currents, the positive terminal of one battery is connected to the negative terminal of the next, and one connection is made between each adjacent battery.
