If a 100 w light bulb and a 75 w light bulb operate from 220 v the bulb has a greater current in it1).75 w2). 100 w

The correct answer is 100 W.

Explanation:

The expression for the power in terms of voltage and the current is as follows;

P=VI                                                                    .......... (1)

Here, P is the power, V is the voltage and I is the current.

It is given in the problem that a 100 W light bulb and a 75 W light bulb operate from 220 V .

Calculate the current for light bulb, 100 W by rearranging the above expression.

Put P= 100 W and V= 220 V.

I= 0.45 A

Calculate the current for light bulb, 75 W by expression (1).

Put P= 75 W and V= 220 V.

I= 0.34 A

Therefore, 100 W light bulb has a greater current in it
