Twelve 6Ω resistor are used as edge to form a cube. The resistance between two diagonally opposite corner of the cube is
The current i will be distributed in the cube branches symmetrically
v1 = ?
If we go from +side of 1 kΩ through 7 V, 6 V and 5V,weget v1 = 7+6 + 5 = 8 V
The voltage vo in fig. P1.1.11 is always equal to
It is not possible to determine the voltage across 1 A source.
Req = ?
In the circuit of fig. P.1.1.31 dependent source
A capacitor is charged by a constant current of 2 mA and results in a voltage increase of 12 V in a 10 sec interval. The value of capacitance is
The energy required to charge a 10 μF capacitor to 100 V is
The current in a 100 μF capacitor is shown in fig. P.1.1.34. If capacitor is initially uncharged, then the waveform for the voltage across it is
This 0.2 V increases linearly from 0 to 0.2 V. Then current is zero. So capacitor hold this voltage.
The voltage across a 100 μF capacitor is shown in fig. P.1.1.35. The waveform for the current in the capacitor is
The waveform for the current in a 200 μF capacitor is shown in fig. P.1.1.36 The waveform for the capacitor voltage is
For 0 ≤ t ≤ 4,
It will be parabolic path. at t = 0 t-axis will be tangent.
