7.
What usually happens to the brightness of identical lamps when another lamp is added in series?
The lamps become dimmer because total resistance increases and current decreases
The lamps always become brighter
The battery stops providing energy permanently
Current becomes infinite
8.
Why can adding an extra cell in series make a lamp brighter?
It increases the potential difference and can increase the current
It removes the conducting path
It turns the lamp into an insulator
It always decreases the circuit energy
9.
Two identical lamps are in series. One lamp is removed and the circuit is reconnected with one lamp. What is likely to happen?
The remaining lamp becomes brighter because total resistance is lower
The remaining lamp cannot light in any circuit
The current must fall to zero
The cell changes into a resistor
10.
Which measurement directly shows how adding components changes the current in a series circuit?
The reading on an ammeter connected in series
The colour of the connecting wires
The mass of the switch
The room temperature only
