What is the unit used for measuring current?

• Watt

• Ohm

• Ampere

• Volt

What is the formula for Ohm's Law?

• V = I/R

• R = VI

What happens in a series circuit if one bulb fuses?

• Only the fused bulb goes out

• All bulbs light up

• All bulbs do not light up

• The circuit becomes parallel

How does resistance change with the length of the conductor?

• Resistance decreases

• Resistance becomes zero

• Resistance increases

• Resistance remains the same

Why does resistance decrease if the cross-sectional area increases?

• Resistance does not change

• Less space for electrons to travel

• More obstacles for the current

• More space for electrons to travel
