applied questions

• State an advantage of connecting voltage sources in a series: The total voltage is doubled, providing more energy to the circuit
• State an advantage of connecting voltage sources in parallel: The total voltage is unchanged, now two sources can share the burden of supplying energy to the circuit. Voltage source will last twice as long
• Essential components of electric circuits:

  1. voltage
  2. connecting wires
  3. one device that converts electrical energy into other forms of energy
• State the advantage of connecting electrical devices in series: the total energy drawn from the source of voltage is reduced
• state an advantage of connecting electrical devices in parallel: each device can be switched off and on independently of other devices in the circuit
