Question

a voltmeter of 1000 ohm resistance reads 200 V when connected across a battery of 60 ohm internal resistance. what is the e.m.f. of the battery ?

Answer 1

HEY!!

____________________________

⏺️R= 1000 ohm,V=200 volt,

⏺️r=60 ohm

⏺️E-V=(E/R+r) x r

⏺️Putting the values,

⏺️E-200=(E/1000+60) x 60

⚫E=212 V

Answer 2

Answer:

212 Volt.

Explanation:

• Here,

• R=1000 ohm,V=200 volt

• r=60 ohm

• Then by

• E-V=(E/R+r) x r

• Putting the values,we get

• E-200=(E/1000+60) x 60

• E=212 V
