Average Voltage And Current

Rms Voltage And Current

What is the average value of alternate voltage and current in a complete cycle ?

Alternating Voltage & Current|Average Value(Mean Value)|RMS Value|Phase And Phase Difference

Assertion : Instruments used for measuring alternating voltage and current have non-uniform divisions on their scales. Reason: Insteruments used for measuring alternating voltage and current are based on heating effect of current.

A circuit consists of a 2 mu F capacitor and a resistor of 1 kOmega . An a.c. source of 12 V, 50 hz is connected across the circuit. Calculate (i) current flowing (ii) voltage across capacitor (iii) phase angle between voltage and current (iv) average power supplied.

Which of the following represents the value of voltage and current at that instant?

Different voltages are applied across a P-N junction and the currents are measured for each value. Which of the following graphs is obtained between voltage and current?
