First questions

1. A current of $0 \cdot 5 + 0 \cdot 3 \sin \omega t - 0 \cdot 2 \sin 2\omega t$ is passed through a moving coil and a moving iron ammeter which are in series. The reading of moving coil and moving iron ammeter will be respectively
2. Two ammeters, one with full-scale current of 1 mA and internal resistance of 100 Ω and the other full-scale current of 10 mA and internal resistance of 25 Ω are in parallel. What is the total current these two meters can carry without any meter out of scale?
3. If two 500 V full-scale voltmeters V, and V, having resistances 200 kΩ/V and 250 kΩ/V, respectively, are connected in series to measure 900 V, then - V, and V, read 400 V each
