Question

A 5.4-V battery is connected to a bulb whose resistance is 3.1Ω. What is the current through the bulb?

Answer 1

Answer:

from ohms law we can say current =emf/resistance=5.4/3.1=1.74

Explanation:

Answer 2

Given:-

☛Voltage of battery = 5.4 V

☛Resistance = 3.1Ω

Find:-

☛Current produces-?

Solution:-

☛According to ohm's law,

$\boxed{\bf{V=IR}}$

where,

v= voltage

I= current

R= Resistance

Put values,

$\sf{\implies 5.4 = I \times 3.1 }$

$\sf{\implies I= \dfrac{5.4}{3.1}}$

$\sf{ \implies I= 1.74}$

Therefore , Current Produces through bulb is 1.74 A.

(Unit of Current = ampere (A))
