Basic electrical Concepts

Proton has a (a)  

• Negative charge
• Positive Charge
• Neutral charge
• All the above

The electron has a  (a)  

• positive charge
• negative  charge
• neutral charge 
• all of the above

The resistivity of the conductor depends on

• area of the conductor.

• length of the conductor.

• type of material.

• none of these.

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms

What is current measured in? (a)  

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is Resistance?

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

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light
