Question

A 6.0 V battery delivers a current of 120 mA to a 46 Ω resistor. The voltage at the battery terminals is: a.4.2 V

b.5.5 V
c.9.6 V
d.8.4 V

Answer 1

V= 5.52 V

Step-by-step explanation:

Given that

V= 6 V

I = 120 mA

R= 46 Ω

We know that

ΔV= R I

ΔV= 120 x 0.001 x 46

V= 5.52 V

So the option b is correct.

Answer 2

terminal voltage will be 5.5 volt

So option (b) is correct optio

Step-by-step explanation:

We have given voltage on the battery V = 6 volt

Current i = 120 mA
`=120* 10^(-3)A`

Resistance R = 46 ohm

We have to find the voltage at the terminal

At terminal there will be resistance

So according to ohm's law V = I R

So voltage
`V=0.120* 46=5.52volt`

So terminal voltage will be 5.5 volt

So option (b) is correct option
