Current Intro Reg Block 2

A term used to describe the number of electrons moving past a fixed point in a conductor in one second is called________.

• Potential Difference

• Molecule

• Current

• Ohms

What is current measured in?

• Ohms

• Amperes

• Volts

• Newtons

In solid conductors, electric current is the flow of

• positive and negative charges.
• electrons.
• negative ions.
• protons.
• none of the above

Which diagram correctly shows the electric field around a negative charge?

• A

• B

• they are both positive

Electrical resistance is measured in

• Volts

• Joules

• Watts

• Amperes

• Ohms

Potential Difference is measured in __.

• Volts

• Watts

• Coulombs

• Amps

What is the correct equation?

• potential difference = charge / time taken

• potential difference = work done / charge

• potential difference = work done / time taken

• potential difference = time taken / charge

If the Voltage stays the same and Resistance is increased, Current will 

• Increase
• Decrease
• Stay the same
• X

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

What is Ohm's Law?

• $R=VI$
  

• V= $\frac{R}{I}$

• $R=\frac{V}{I}$

• $V=\frac{W}{q}$
