Question

Electrical Power (P) is measured in watts using the formula P = VI, where V is the voltage in volts and I is the current in amperes. If 60 volts run through a light bulb of 84 watts, how much current is flowing through the light bulb?

Answer 1

1.4 amperes

Explanation:

As we know that formula to find power is, P= VI

where, v is voltage and I is current

We are given that P= 84 watts & V= 60 volts

We have to find the value of current that is flowing through it

than, I=
`(P)/(V)`

I=
`(84)/(60)`

I=1.4 amperes

Hence the current s 1.4 amperes

Hence, the correct answer is 1.4 amperes
