Electric circuits assignment
Which circuit prevents the flow of current? - correct answer ✔open
Use the circuit diagram to decide if the lightbulb will light. Justify your answer.
(1) - correct answer ✔Sample Response: The lightbulb will light because this
is a parallel circuit. Even though the switch is open in one branch, the branch
the lightbulb is in forms a closed circuit, allowing the current to flow through
the bulb.
Use the circuit diagram to decide if the lightbulb will light. Justify your answer.
(2) - correct answer ✔Sample Response: The lightbulb will not light because
this is a short circuit. The branch without the bulb has almost no resistance, so
all the current will flow through that branch instead of flowing through the bulb.
Which circuit has the higher equivalent resistance? - correct answer ✔series
circuit
What is the equivalent resistance in this circuit? - correct answer ✔1. 15 Ω
2. 3 A
Use the circuit diagram to determine the voltage drop across the 8 Ω resistor.
- correct answer ✔4 V
If the current in this circuit is 3 A, what must be the value of R3? - correct
answer ✔5 Ω
In a series circuit with three resistors connected to a power source, what
would happen to the equivalent resistance and current if you removed any
