If you have successfully completed the questions asked in Basic Electronics Questions #1 and Basic Electronics Questions # 2 here is a new set of  questions to test your knowledge on basic electrical and electronics:

1. Resistance is that property which opposes current flow.
2. The unit of resistance is the Ohm (Symbol: Omega - Ω )
3. Define conductance. Answer : Conductance is the ease with which a material passes current flow. It is the reciprocal of resistance.
4. Three types of resistance construction are wire-wound, carbon-composition and deposited-film
5. A variable resistor is called a potentionmeter
6. What is Power? Answer: Power is the amount of work done in a specific length of time.
7. The unit of electrical power is the Watt
8. Write the basic power formula P = IE
   
9. The basic law of magenetism is like poles repel, unlike poles attract
10. The force which produces the flux lines in a coil is called magnetomotive force
11. The ampere-turn is the unit of magnetomotive force
12. The ability of a material to concentrate magnetic flux is called permeability
13. An Ammeter is used to measure Current flowing in a circuit
14. A Voltmeter is used to measure Voltage
15. An ohmmeter is used to measure Resistance
