Compared to thin wires, electrical resistance in thick wires is:

• greater
• less
• the same

When one bulb in a series circuit containing several light bulbs burn out:

• the other bulbs burn brighter.
• nothing changes in the rest of the circuit.
• none of the other bulbs will light up.

Current is measured in:

• joules
• ohms
• amperes
• watts
