Two resistors `400Omega` and `800Omega` are connected in series with a `6V` battery. It is desired to measure the current in the circuit. An ammeter of `10Omega` resistance is used for this purpose figure. What will be the reading in the ammeter? Similarly, if a voltmeter of `10,000Omega` resistance is used to measure the potential difference across the `400Omega` resistor, what will be the reading in the voltmeter?

Two resistors, 400 Omega, " and "800 Omega are connected in series with a 6 battery. It is desired to measure the current in the circuit. An ammeter of 10 Omega resistance is used for this purpose. The reading of ammeter will be N/(1210) A. Similarly, if a voltmeter of 1000 Omega resistance is used to measure the potential difference across the 400 Omega resistor, the reading of voltmeter is P/19V . Then the value of N and P are:

Two resistors 4 Omega and 800 Omega are connected in series with a 6V battery. The potential difference measured by voltmeter of 10kOmega across 400 Omega resistor is
