Question

2. A bulb of 100 W is connected across a source
of 200 V. Find the current drawn by it.​

Answer 1

Answer:

Power = Voltage x Current

P = VI

Then, solve for current:

I = P / V = 100 W / 220 V

So, your current becomes:

I = 0.4545A which is approximately = 0.45

Answer 2

Answer:

0.45 amperes

Explanation:

Power(P) = Rate of work done

Power(P) = Work(W) / Time(t)

Power(P) = V × q / t # V = Work / Charge = W / q

# W = V × q

Power(P) = V × I # I = q / t

I = P / V

I = 100 / 200

I = 5 / 11

I = 0.45 amperes.
