WIRES JOINTS SOLDERING UG CABLES - Quiz

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

Cost is less More flexible Less voltage drop More insulation resistance

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

3) What is the unit for Quantity of electricity?

Mho Coulomb Volt /second Ampere/second

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
