current

An electric field of 0.01 V/m is applied along the length of a copper wire of circular cross-section with diameter 1 mm. Copper has a conductivity of 5.8 × 10^7 S/m. The current (i...

In the given circuit, the current Ix (in mA) is _________.

In the circuit shown below, the current i flowing through 200 Ω resistor is _________ mA (rounded off to two decimal places).

In the circuit shown, if v(t) = 2 sin(1000 t) volts, R = 1 kΩ and C = 1 µF, then the steady-state current i(t), in milliamperes (mA), is

Two identical copper wires W1 and W2, placed in parallel as shown in the figure, carry currents I and 2I, respectively, in opposite directions. If the two wires are separated by a...
