voltage* current
dynamo
convert mechanical energy into electrical energy
faraday constant
it represent magnitude of electric charge per mole of electron
anode
is negative charge
cathode
positive charge
filament in lighting bulb
tungsten
primcipke of fuse
heating effect of electricity
domestic electric wiring connection is basuically
parallel connection
magnitude of resistance of human body
10^4 ohm
what gas are filled in flurscent tube
mercury and neon
how does white light produce in tube
by oscillating the molecule
if potential difference and current flowing through wire increased twice each then electric powwer
increase 4 times
mobile phone charger
step down transformer
lighting conductor metal
copper
Meissner Effect
uperconductors expel magnetic fields from their interior when they transition into the superconducting state, causing them to repel magnets and allowing for magnetic levitation.
which liquid is use for superconductor
liquid helim
resisitance of semi conductor on heating
decrease
electric conduction in semi conductor takes place in both electron and holes
at absolute zero the electric resistance in semi conductor is
infinite
control rod in nuclear reactor is made of
barium and cadmium
which particles is claimed to have invented which rebut theory of relativit
microwave photon
cyclotrons are used to accelerate
protons
which is used to confirm whether gamma emitting isotope or not
scintillation counter
