What is Electric Current?

• The flow of protons

• The flow of Neutrons

• The flow of electrons

• The flow of higgs boson

Switch is otherwise called as

• Circuit

• Key

• Current

• Voltage

What is electric circuit?

• Continuous open path

• Continuous irregular path

• Continuous closed path

What is open circuit?

• An electrical circuit in which the continuity is broken so that current does not flow.

• An electrical circuit in which the continuity is not broken and has a complete path for current to flow.

• An electrical circuit in which the continuity is broken and has a complete path for current to flow.

• Ammeter

Choose the correct option

• 1 mA = 10^–5 A

  1 μA = 10^–7 A

• 1 mA = 10^–8 A

  1 μA = 10^–5 A

• 1 mA = 10^–3 A

  1 μA = 10^–6 A

• 1 mA = 10^–6 A

  1 μA = 10^–3 A
