Electromagnetic waves emitted from the antenna are ??
View Answer Explanation
An alternating current or voltage ??
A capacitor of capacitance 30µF is charged by a constant current of 10mA. If initially, the capacitor was uncharged what is the time taken for the potential difference across the capacitor to reach 300V ??
Electromagnetic waves travel in free space with the speed of ??
To find the r.m.s value of an alternating current mathematically we need to have ??
An electromagnetic wave consists of ??
An alternating current is represented by the equation I = I∫sinπt which of the following equation represents an alternating current of frequency and amplitude twice that of the above current ??
Waves emitted from the antenna are ??
pure resistor circuit the voltage and current are ??
If the capacitance of L-C circuit is made four times then the frequency of the circuit becomes ??
When A.C current passes through a capacitor then the current relationship will be ??
