Electronic component used to reduce current and voltage levels in circuit:

• Resistor

• Diode

• Capacitor

• Transistor

Electronic component that allows current to flow in one direction only:

• Diode

• Resistor

• Capacitor

• Transistor

The difference in charge between two points:

• Voltage

• Current

• Resistance

• Power

Letter used to represent Amps:

• I

• V

• R

• Ω

The current through a 330 Ω resistor with 5V applied across it:

• 15mA

• 0.15A

• 1515A

• 55mA

If the voltage is increased in a circuit, the resistance must be increased to keep the current the same.

• True

• False

• It depends

• Bruh

Will a 1/4 W, 470 Ω resistor over heat with 12V applied across it?

• Yes

• No

• only if it's over 30°

• It depends

Electricity wants to move from...

• higher to lower voltage levels

• higher to lower resistance levels

• higher to lower current levels

• higher to lower power levels

Providing a path directly from the positive to negative side of a power supply is called...

• short circuit

• open circuit

• long circuit

• mini circuit
