Grade 11Electric Current
We have two identical filament bulbs joined in two different circuits such that V is the voltage supplied to first one and 3I is the current flowing through it. The other bulb has 3V voltage and I is the current flowing through it. Which one will glow more bright.
(IN SHORT WHICH DEVICE WILL BE MORE EFFICIENT ONE HAVING MORE CURRENT OR MORE VOLTAGE?)
If your answer is voltage, then why?
What would be your answer if the same question is applied for motors in place of bulbs (don’t forget motor works on the principle of magnets which is due to the flow of current)
EFFICIENCY OF AN APPLIANCE DEPEND ON VOLTAGE OR CURRENT?
