Question

Q1.What will be the current dream by an electric bulb of 40 watts when it is connected to a source of 220 volts.​

Answer 1

Explanation:

✬ Current = 0.18 A ✬

Explanation:

Given:

Power of bulb is 40W.

Voltage across the bulb is 220 V.

To Find:

What current will be drawn ?

Formula to be used:

Power = Voltage × Current

Solution: Here we have

P = 40 W

V = 220 V

I = to be calculated

Put the values on the values on the formula

⟹ P = V × I

⟹ 40 = 220 × I

⟹ 40/220 = I

⟹ 4/22 = I

⟹ 2/11 = I

⟹ 0.18 A = I

Hence, the current drawn by the bulb will be 0.18 ampere.

Hence, the current drawn by the bulb will be 0.18 ampere.Power is denoted by P , voltage by V and current by I.

Hence, the current drawn by the bulb will be 0.18 ampere.Power is denoted by P , voltage by V and current by I.S.I unit of current is ampere denoted by A.

Answer 2

answer here⬇⬇

I = p/ V

= 40/ 220

=0.18 A

➡ the current drawn by an electric bulb of 40W is 0.18 A.
