The lissajous pattern appearing on the screen of a CRT, when two sinusoidal voltages of equal frequencies, which are in phase with each other are applied to the CRO is
Which one of the following types of landline telemetry method has the advantage of simplicity and is free from noise, leakage and supply voltage variations?
When the voltage across a battery is measured using a D.C. potentiometer, the reading shows 1.08 V. But when the same voltage is measured using a Permanent Magnet Moving Coil (PMMC) voltmeter, the voltmeter reading shows 0.99 V. If the resistance of the voltmeter is 1100 Ω, the internal resistance of the battery, in Ω, is
A capacitance transducer uses two quartz diaphragms of area 750 mm2 separated by a distance 3.5 mm. The capacitance is 370 pF. When a pressure of 900 kN/m2 is applied, the deflection is 0.6 mm. The capacitance at this pressure would be:
