Vocabulary
An electric circuit with only one branch is?
Series Circuit
An alarm clock draws 0.5 A of current when connected to a 120 volt circuit. Calculate the resistance.
R=240 Ohms
Voltage is how powerful electricity is, current is the path in which electricity moves, resistance is when something doesn't let the current through easily.
What happens to a parallel circuit when a bulb is unscrewed?
All the bulbs will still be lit up
What unit of measurement symbolizes volts?
V
Contains two or more branches for a current is?
Parallel Circuit
A walkman uses a standard 1.5 volt battery. How much resistance is in the circuit if it uses a current of 0.01 A ?
R=150 Ohms
The current is the same at all points in the circuit?
Series Circuit
What happens to a series circuit when a bulb is unscrewed?
All the bulbs will turn off
What unit of measurement symbolizes current?
A
Electrical Power
What happens to the current in a circuit if a 10 Ohms resistor is removed and replaced by a 20 Ohms resistor?
The volts will be doubled
What is the formula for resistance?
R=E/I
How do parallel and series circuits differ from each other?
Parallel circuits are connected through multiple circuits while a series circuit is connected through one large circuit.
What unit of measurement symbolizes resistance?
Ohm or omega symbol
Device that prevents circuit from overheating and causing fire is?
Circuit Breaker
If a toaster produces 12 Ohms of resistance in a 120 volt circuit, what is the amount of current in the circuit?
I=10 A
What is the formula for voltage?
E=IR
What is the function of a circuit breaker?
To interrupt current flow after a fault is detected.
What year was Mrs.Perez born?
1976
When any part of a series circuit is disconnected, there is no current through the circuit is?
I=20 A
What is the formula for current?
I=E/R
What happens to the brightness of each bulb as more bulbs are added to a circuit?
The bulbs become brighter due to more energy going through the circuit.
What is Mrs.Perez middle name?
Shawntel
