  • 12 volts
  • 24 volts
  • 1.3333
  • 48 volts

  • 10V
  • 2.5V
  • 7V
  • 0.4V
Q.13
In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through the resistor increases. Why does this occur?
  • As the electrons are sped up, they bunch closer together.
  • As the electrons have more energy, they vibrate more rapidly.
  • As the electrons are pushed more by the battery, they move faster through the circuit.
  • As the distance around the circuit increases, the electrons take longer to travel around.
Q.14
Laser printers work with the use of heat and positive and negative charges. The laser etches a negative charge on spots of the printer drum in the form of text or images.
