एक मूविंग आयरन उपकरण 3 A पर 30° का विक्षेपण दिखाता है। जब धारा बढ़ाकर 5 A कर दी जाती है तो विक्षेपण क्या होगा?

In a Wheatstone bridge, the ratio arm resistances are P = 10000 Ω and Q = 10 Ω. The adjustable arm resistance S can have a maximum value of 1000 Ω. The battery voltage is 10 V with negligible resistance. The maximum value of unknown resistance R that can be measured is:

A current i = 5 + 14.14 sin(314t + 45°) A is passed through a center-zero PMMC meter, a hot-wire ammeter, and a moving-iron ammeter. The respective readings will be:
