Elect. Series & Parallel

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel
• series
• open
• closed

What kind of circuit is this?

• Series
• Consecutive
• Parallel
• Training

This circuit does not work because…

• the bulbs are not connected properly

• the single cell is not powerful enough

• there is a break in the circuit so it's "open"

• there is a short crcuit

what is this symbol for?

• light bulb
• switch
• battery
• resistor

Find the current in this circuit. ...V=IR.......I=V/R.....R=V/I

• 55 A

• 6050 A

• 22 A

• 2 A

Find the current in this circuit. (Pretend they are regular Ohms and NOT kOhms) I=V/R....then...I total = I1 + I2 + I3

• 13 A

• 5.4 A

• 14.4A

• 0.69 A

Find the equivalent resistance of this circuit.

• 8 Ohms

• 9 Ohms

• 16 Ohms

• 19 Ohms

Which of the following is true of the circuit when switch S is open

• neither R1 nor R2 work

• both R1 and R2 work

• only R1 works

• only R2 works
