Question

A bulb is connected across a 3.0 V power Source, if the current passing through the Bulb is 1.75 A, what is the power rating of the Bulb?

Answer 1

Answer:

It will be 5.0 VATT

Explanation:

STEP 1:Enurmate the given values

Given:

l=1.75 A

V=3V

Step 2:Identify what is being asked.

Required:

Resistance

Step 3:Solve for Resistance

Equation:

The formula for Resistance is given by:

R=V/I

where:R-Restiance

I=Current

V=Voltage

Solution:

Substitution the value of V and I in the formula

R=(3 V)/(1.75 A)

R=ii1.71
