Electric circuits: quiz
A series circuit contains a 30 Ω resistor, a 20 Ω resistor, and a 10 Ω resistor. The power supply
provides 100 V to the circuit. - Answer 1.7 A
Which correctly describes the number of one type of component in this circuit? - Answer 3
resistors
The cause of a fire in a computer is described as an incorrectly wired circuit.
Which statement best explains the likely cause of the fire? - Answer The wiring contained a
short circuit, so the reduced resistance caused an increase in current.
Which are disadvantages of series circuits? Check all that apply. - Answer A break in one wire
causes all current to stop.
If one bulb goes out, the others go out.
What is the current in the 50 Ω resistor? - Answer 1.2 A
What is the purpose of the component represented by the symbol? - Answer to measure
voltage
Which circuit component should Keisha use to start or stop the current in the circuit? - Answer
W
In which region should she place each label? - Answer Label 1: Y
Label 2: W
A power source that provides a current of 1.6 A to two 5 Ω resistors connected in series is
moved to a parallel circuit that consists of three identical resistors. In the parallel circuit, the
overall current is 2.0 A. - Answer 24 Ω
A disrupted circuit in which the current bypasses its proper path is a - Answer short circuit
