WIRES JOINTS SOLDERING UG CABLES - Practice Mode

1) What is the advantage of stranded conductor over solid conductor?

Cost is less More flexible Less voltage drop More insulation resistance

Correct Answer: More flexible

2) What is the current capacity of the 16 Amp. Cable, if it is protected by coarse excess current protection?

11:00 AM 13 A 15 A 18 A

Correct Answer: 13 A

3) What is the unit for Quantity of electricity?

Mho Coulomb Volt /second Ampere/second

Correct Answer: Coulomb

Explanation:

The unit of quantity of electricity is called the coulomb.

A coulomb is the quantity of electricity which passes any point in a circuit in 1 second when a steady current of 1 ampere is flowing. It follows that the total quantity of electricity Q, in coulombs, which passes any point in an electric circuit is given by multiplying the current I, in amperes, by the time t, in seconds.

4) What formula is used to find Electro Motive Force (EMF)?

EMF = Potential difference ? voltage drop EMF = Potential difference + voltage drop EMF = Potential difference + voltage drop/2 EMF = Potential difference + 2 x voltage drop

Correct Answer: EMF = Potential difference + voltage drop

5) What is the current rating factor for close excess current protection of cable?

0.81 0.92 1.23 1.5

Correct Answer: 1.23
