Series and Parallel tutorial

Identify the resistors in SERIES.

• R1-R2

• R2-R3

• R3-R4

• None of the above

Parallel circuits are

• Circuit that has only one path for current to travel

• Has more than one path for current to travel

• A circuit that does not allow electricity to travel through it

• Magnets can cause electric current

When resistors burn out, they usually short.

• True

• False

In parallel circuit if one of the light bulbs burn out the rest ..

• Stop the flow of electricity

• Can still light up

• will not light up

• light bulb will burn out

A voltage divider is a common application of a series-parallel circuit.

• True

• False

In a parallel circuit, if one connection is broken, all of the connections stop working.

• True

• False

As more and more

resistors are added in parallel to a circuit, the equivalent resistance of

the circuit ____________ (increases, decreases) and the total current of

the circuit ____________ (increases, decreases).

• Increase, decrease

• increase, increase

• Decrease, Increase

• Decrease,decrease

How to describe a series circuit? All statement is true ,EXCEPT

• Only ONE path for current to flow in a closed circuit

• Current remains the SAME in all parts of the circuit

• Voltage is DIFFERENT across each component

• Current is DIFFERENT through each component of the circuit (according to their resistance values)

How to describe parallel circuit? All statement is true, EXCEPT

• Voltage remains the same across each component of the circuit

• Current is DIFFERENT through each component of the circuit (according to their resistance values)

• Voltage remains Different accross each component of the circuit

• More than one path for current to flow in a closed circuit

Given V=20V, calculate the value of R when I is 2mA?

• 10 ohm

• 100 ohm

• 10 k ohm

• 100 k ohm
