Question

Answer these questions

Answer 1

answer 1...
pure tungsten has a high melting point that's why it's used in filament of electric bulb
answer 2...
the potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of charge from one point to another.
answer 3..
the sum of combination of resistance is equal to the total resistance.
answer 5...
the resistivity of the conductor is numerically equal to the resistance which is 1 meter long in area of cross section is 1 square meter.
answer 6..
(a) r1+r2+r3=2+3+4ohm
= 9 Ohm
the overall resistance which is connected in series is 9 Ohm.
