What is the Ohm's law?

• R x V : I

• I x R, V : I, V : R

• V x R, I : V

• O + A x I

What is an ameter for?

• For measuring the resistance of a bulb

• It's a toy

• Measuring volts in a light bulb

• Measuring either direct or alternating electric current

What is a voltmeter for?

• For measuring the resistance of a light bulb

• Measuring electrical potential difference between two points in an electric circuit

• Measuring current in a circuit

• It's a toy

If a lightbulb blows in a parallel circuit, what happens?

• The voltage drop is 6.0 V across each bulb and they all glow

• That we have to run

• That the bulb had lot's of resistance

• Nothing of above it's another reason not specified in the others

What happens if a lightbulb blows in a series circuit?

• It destroys the switch and the battery

• I don't know

• That the other light bulb still worcks the same because it has another cable completely different crossing on it

• The power supply to all other bulbs is cut off

What is a volt?

• What is a volt?

• Is the derived unit of the International System for electric potential, electromotive force and electric voltage

• Is the charge of the bulb it also shows the bulb's resistence

• Other

What Is the total current in a Series Circuit?

• It's 4.9 ametres.

• The current is the same magnitude at any point in the circuit

• The current of a series circuit is 5.6 volts

• This is the correct answer

What is the function of a Switch in a parallel electrical circuit?

• Switches are to charge a circuit

• I don't know

• Switches are often used when you want the convenience of controlling a circuit from two different locations.

• Switches are very important without one electrons can't flow

What is a series circuit?

• All components share the same Voltage

• There is only one path for current to flow

• The series circuit has much more volts than paralel circuits

• It's hard

What is a characteristic of the paralel circuit?

• There is only one path for current to flow

• All components share the same Voltage

• I don't know

• It has less voltge than series circuit
