Two batteries, one of emf 18V and internal resistance 2Ω and the other of emf 12 and internal resistance 1Ω , are connected as shown. The voltmeter V will record a reading of are connected as shown.The voltmeter V will record a reading of one of emf 18V and internal resistance 2Ω and the other of emf 12 and internal resistance 1Ω Two batteries December 1, 2020 Category: Cengage NEET by C.P Singh , Chapter 3 - Current Electricity , Part 2 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related The series combination of two batteries, both of the same emf 10 V, but different internal resistance of 20 Ω and 5 Ω, is connected to the parallel combination of two resistors 30 Ω and R Ω. The voltage difference across the battery of internal resistance 20 Ω is zero, the value of R (in Ω) is : _______A voltmeter having a resistance of 1800 Ω is employed to measure the potential difference across 200Ω resistance, which is connected to dc power supply of 50 V and internal resistance 20Ω. What is the approximate percentage change in the potential difference across 200Ω resistance as a result of connecting the voltmeter across it?Two resistors of 500Ω and 300Ω are connected in series with a battery of emf 20V.A voltmeter of resistance 500Ω is used to measure the p.d across the 500Ω resistor. The error in the measurement is.
