Question

Calculate the energy transferred in bulb X in 3Seconds if the current in the circuit is 2 Amperes

Answer 1

Gives

Time(t)=3sec

Current (i)=2Amp

Resistance=x ohm

Power

$P=i^2X$

Energy transfer in 💡(bulb)

$P=\frac{E}{t}$

$E=P\times t$

$E=i^2Xt$

Put values

$E=2^2\times3X$

$E=12XJ$
