What happens to the power dissipated by a resistor as the current through the resistor increases?
The unit of power is the Watt (W). When the voltage is increased, the current, I, increases and the power dissipated by the resistor, R, increases. When the value of the resistor is increased, I decreases and the power dissipated by the resistor, R, decreases.
What happens to the reading of A1 A2 A3 and A when the bulb B2 gets fused?
Hence, the ammeter readings would be where A1 shows 1 ampere, A2 shows zero as bulb B2 blows off, A3 shows 1 ampere and A shows 2 amperes, the total current in the circuit. Was this answer helpful?
What happens to the glow of the other two bulbs when the bulb b1 gets fused II What happens to the reading of A1 A2 A3 and A when the bulb B2 gets fused III how much power is dissipated in the circuit when all the three bulbs glow together?
the glow of the bulbs B2 and B3 will remain the same as the V and R remains the same. When bulb 2 gets fused: Reading on A1 is 1 ampere, reading on A2 is 0 ampere, reading on A3 1 ampere and reading on A is 2 ampere.
What happens to the glow of the other two bulbs when the bulb be one gets fused?
Answer : (i) There will be no effect on glow of other two bulbs and will remain same when B1 gets fused because glowing of bulb depends on power and the potential difference and resistance remains same of other two bulbs. So, current will be distributed in both the bulbs as 1 A each.
What will happen to the glow of the other two bulbs If the bulb b3 gets fused?
(i) Since bulbs B1,B2andB3 are in parallel, when bulbs B1 gets fused, the pd across B2andB3 does not change. Thus, the glow of bulbs B2andB3 remains unchanged. (ii) When the bulbs B2 gets fused, no current flows through A2 and as such it shows zero reading.
What happens when a bulb gets fused?
When the filament of a bulb is broken then the bulb is said to be fused. When it gets fused it does not emit light. When the bulb gets fused, the electric current is not allow to pass through the filament and the bulb does not glow because the filament of the bulb is broken.
What happens to the reading of a when the bulb b3 gets fused?
Now, let us consider the case when the bulb B2 gets fused. In this condition, there will be no current passing through ammeter A1. Therefore it will show zero reading. Because of the parallel connection, there will not be any change in the readings of the other two ammeters.
Will the bulb in the two circuits glow with the same brightness justify your answer?
No the bulbs won’t glow with the same brightness in both circuits. The bulb in parallel circuit will glow brighter than when connected in series.
Why the bulb gets fused if it is operated at higher potential than its power rating?
Why does an electric bulb get fused if it is operated at a higher potential than its power rating…?? Because the high voltage, filament of the bulb becomes more heat up and bulb gets fused. because of high voltage.
What happens when a bulb gets fused Class 7?
If one bulb gets fused, the circuit will break and all bulbs will be turned off.
Can electricity pass through a fused bulb?
When bulbs have a melted filament, they have fused. Due to the gap in the filament, electricity is unable to flow through the filaments of fused bulbs, preventing them from lighting up.
