Circuit Components
This component limits the flow of electric current.
What is a Resistor
This part supplies electrical energy to the circuit.
What is a Power Source
This term describes the positive and negative orientation of a component or power source.
What is polarity
This type of circuit has only one path for current.
What is series
This adjustable component is also called a variable resistor.
What is potentiometer
This component produces light when current flows through it in the correct direction.
What is a LED
These carry electric current between components.
What are paths (wires)
These two symbols identify the electrical terminals of a battery.
What is positive and negative
This type of circuit has multiple paths for current.
What is Paralell
This is the energy-using part of a circuit, such as a motor or LED.
What is load
This component stores electrical energy and releases it later.
What is a Capacitor
This part uses electrical energy to do work.
What is a load
On a typical through-hole LED, this longer leg is the positive terminal.
Anode
In this type of circuit, one broken component can stop current through the entire circuit
What is series
This component is commonly connected in series with an LED to protect it from too much current.
What is a resistor
This component converts electrical energy into movement.
What is a Motor
This part opens or closes a circuit to control current.
What is a switch
On a typical through-hole LED, this shorter leg is the negative terminal.
What is a cathode
In this type of circuit, other branches can continue working when one branch breaks.
What is Parallel
This type of circuit would be better for two lights that need to operate independently
What is parallel
This component can act as an electronic switch
What is a transistor
A circuit needs this kind of path for current to flow continuously.
What is a complete or closed path
An LED connected backward in a simple DC circuit will usually do this.
Do nothing, not light up
In a parallel circuit, this electrical quantity is the same across each branch.
What is voltage
You build a circuit with a battery, switch, resistor, and LED. When you close the switch, the LED does not light up. You discover that the LED is connected backward. What is the problem, and how would you fix it?
The LED has incorrect polarity. Reverse the LED so its positive side (anode) and negative side (cathode) are connected in the correct direction.
