POE Electricity Vocab Part 2

What is true about the current through a series circuit?

• Current is added up across the light bulbs

• The same current flows through all three light bulbs.

• Current is the same voltage as the battery

• The electrical current is divided between the three light bulbs.

what is this symbol for?

• light bulb
• switch
• battery
• resistor

NGSS.HS-PS2-5

A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit.

• Series

• Parallel

• Open

• Dihexihedral

"The total current in a parallel circuit equals the sum of the individual branch currents."

• Ohm's Law

• Kirchhoff's Voltage Law

• Kirchhoff's Current Law

• Bolen's Law

"The sum of all voltage drops in a series circuit equals the total applied voltage." This is know as what?

• Ohm's Law

• Kirchhoff's Voltage Law

• Kirchhoff's Current Law

• Bolen's Law

What is the unit of measurement for Power?

• Joules
• Newtons
• Watts
• Meters

How to you calculate the total resistance in a series circuit?

• R1 + R2+ R3

• R1 - R2 - R3

• 1/R1 + 1/R2 + 1/R3

• R1 = R2 = R3

How do you calculate total resistance in a parallel circuit?

• R1 + R2 + R3

• R1 - R2 - R3

• 1/R1 +1/R2 + 1/R3 = 1/RT

• R1 = R2 = R3

Resistance is measured in ___. 

• watts. 
• amps.
• ohms.

Voltage is measured in __.

• volts.
• watts.
• coulombs.
