Question

A 100watt bulb is operated by 240volts , the current through the bulb will be

Answer 1

Explanation:

Power= voltages*current

100 =240*I

current I=10/24

=5/12

=.4166A

Answer 2

The current flowing through the bulb is 0.416 A.

Explanation:

Given that,

Power of the bulb, P = 100 W

Voltage, V = 240 volts

We need to find the current flowing through the bulb. The power of an electrical appliance is given by :

$P=V\times I$

I is the current

$I=\dfrac{P}{V}$

$I=\dfrac{100\ W}{240\ V}$

I = 0.416 A

So, the current flowing through the bulb is 0.416 A.
